Let's divide 40645260 by 253
We want to figure out the number of times 40645260 can be divided by 253.

On to step 1:
253 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
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 253

Advancing to step 2:
253 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 253

Step 3:
406 divided by 253 is 1 with a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 253 away from 406, we end up with 153.
Grab the next digit (4) from the dividend, add it to 153, then carry on: 1534 / 253

Let's proceed to step 4:
253 goes into 1534 6 times with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 16 after subtracting 1518 from 1534.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 253

Advancing to step 5:
253 can be fit into 165 0 times, resulting in a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we take 0 away from 165, we end up with 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 253

On to step 6:
When dividing 1652 by 253, we get 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 1606.0
Subtracting 1518 from 1652 leaves us with 134.
Fetch the next digit (6) from the dividend, attach it to 134 and continue: 1346 / 253

Advancing to step 7:
When dividing 1346 by 253, we get 5 with a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 16065.0
If we subtract 1265 from 1346, we get 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 253

Advancing to step 8:
The number 253 fits into 810 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 160653.0
Deduct 759 from 810 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
When dividing 510 by 253, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 160653.2
Subtract 506 from 510 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 253, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 160653.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 253, we get 1 with a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 160653.201
Subtract 253 from 400 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 12:
The number 253 fits into 1470 5 times, leaving a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 160653.2015
The remainder is 205 after subtracting 1265 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 13:
The number 253 fits into 2050 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 160653.20158
Subtracting 2024 from 2050 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
The number 253 fits into 260 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 160653.201581
The remainder is 7 after subtracting 253 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 15:
253 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 160653.201581
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
253 can be fit into 700 2 times, resulting in a remainder of 194.
The next digit of our result is 2. 
Result so far: 160653.20158102
Subtracting 506 from 700 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Our division results in 160653.20158102 with a remaining 1.94e-07.
