We look at the division of 45436964 by 373 
We want to figure out the number of times 45436964 can be divided by 373.

Going ahead to step 1:
373 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 373

Advancing to step 2:
45 divided by 373 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 373

Moving on to step 3:
When dividing 454 by 373, we get 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 373 from 454, we get 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 373

On to step 4:
When dividing 813 by 373, we get 2 with a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 746 from 813 and we're left with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 373

Step 5:
676 divided by 373 is 1 with a remainder of 303.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we subtract 373 from 676, we get 303.
Fetch the next digit (9) from the dividend, attach it to 303 and continue: 3039 / 373

Advancing to step 6:
The number 373 fits into 3039 8 times, leaving a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
Subtract 2984 from 3039 to get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 373

Going ahead to step 7:
The number 373 fits into 556 1 times, leaving a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 12181.0
If we subtract 373 from 556, we get 183.
Fetch the next digit (4) from the dividend, attach it to 183 and continue: 1834 / 373

Going ahead to step 8:
1834 divided by 373 is 4 with a remainder of 342.
Record the quotient 4 as the next digit in the result. 
Result so far: 121814.0
Deduct 1492 from 1834 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 9:
3420 divided by 373 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 121814.9
Subtract 3357 from 3420 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
373 goes into 630 1 times with a remainder of 257.
Write down 1 as next digit of the result. 
Result so far: 121814.91
If we take 373 away from 630, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 11:
If we divide 2570 by 373, we get 6 and a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 121814.916
If we subtract 2238 from 2570, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 12:
3320 divided by 373 is 8 with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 121814.9168
Deduct 2984 from 3320 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 13:
If we divide 3360 by 373, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 121814.91689
If we subtract 3357 from 3360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
The number 373 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 121814.91689
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 15:
373 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 121814.91689
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 121814.91689, and the remainder is 3e-06.
