We're dividing 45515757 by 401 
We want to figure out the number of times 45515757 can be divided by 401.

On to step 1:
401 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 401

Advancing to step 2:
401 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 401

Let's proceed to step 3:
The number 401 fits into 455 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 54 after subtracting 401 from 455.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 401

Let's proceed to step 4:
When dividing 541 by 401, we get 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 401 from 541 and we're left with 140.
Take the next digit (5) from the dividend and append it to 140, then repeat: 1405 / 401

Advancing to step 5:
The number 401 fits into 1405 3 times, leaving a remainder of 202.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 1203 away from 1405, we end up with 202.
Include the next digit (7) from the dividend after 202, then repeat: 2027 / 401

Going ahead to step 6:
401 goes into 2027 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 1135.0
Subtract 2005 from 2027 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 401

Going ahead to step 7:
If we divide 225 by 401, we get 0 and a remainder of 225.
Put 0 as the next digit of the answer. 
Result so far: 11350.0
Subtract 0 from 225 to get 225.
Fetch the next digit (7) from the dividend, attach it to 225 and continue: 2257 / 401

Let's proceed to step 8:
The number 401 fits into 2257 5 times, leaving a remainder of 252.
Put 5 as the next digit of the answer. 
Result so far: 113505.0
If we subtract 2005 from 2257, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 9:
401 goes into 2520 6 times with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 113505.6
The remainder is 114 after subtracting 2406 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
401 goes into 1140 2 times with a remainder of 338.
The next digit of our result is 2. 
Result so far: 113505.62
If we take 802 away from 1140, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 11:
401 can be fit into 3380 8 times, resulting in a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 113505.628
The remainder is 172 after subtracting 3208 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 12:
If we divide 1720 by 401, we get 4 and a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 113505.6284
Deduct 1604 from 1720 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 13:
The number 401 fits into 1160 2 times, leaving a remainder of 358.
Put 2 as the next digit of the answer. 
Result so far: 113505.62842
Subtracting 802 from 1160 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 14:
3580 divided by 401 is 8 with a remainder of 372.
Record the quotient 8 as the next digit in the result. 
Result so far: 113505.628428
The remainder is 372 after subtracting 3208 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 15:
When dividing 3720 by 401, we get 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 113505.6284289
Subtract 3609 from 3720 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 16:
401 goes into 1110 2 times with a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 113505.62842892
Subtract 802 from 1110 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 113505.62842892, and the remainder is 3.08e-07.
