We look at the division of 39512734 by 253 
We want to figure out the number of times 39512734 can be divided by 253.

Step 1:
The number 253 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 253

On to step 2:
If we divide 39 by 253, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 253

Let's proceed to step 3:
When dividing 395 by 253, we get 1 with a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 253 from 395 to get 142.
Include the next digit (1) from the dividend after 142, then repeat: 1421 / 253

Moving on to step 4:
1421 divided by 253 is 5 with a remainder of 156.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 1265 from 1421 and we're left with 156.
Grab the next digit (2) from the dividend, add it to 156, then carry on: 1562 / 253

Going ahead to step 5:
253 goes into 1562 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtract 1518 from 1562 to get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 253

On to step 6:
253 goes into 447 1 times with a remainder of 194.
Write down 1 as next digit of the result. 
Result so far: 1561.0
Deduct 253 from 447 and we're left with 194.
Take the next digit (3) from the dividend and append it to 194, then repeat: 1943 / 253

Advancing to step 7:
When dividing 1943 by 253, we get 7 with a remainder of 172.
Write down 7 as next digit of the result. 
Result so far: 15617.0
If we take 1771 away from 1943, we end up with 172.
Fetch the next digit (4) from the dividend, attach it to 172 and continue: 1724 / 253

Let's proceed to step 8:
The number 253 fits into 1724 6 times, leaving a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 156176.0
Subtracting 1518 from 1724 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 9:
When dividing 2060 by 253, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 156176.8
If we subtract 2024 from 2060, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 253 fits into 360 1 times, leaving a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 156176.81
Subtract 253 from 360 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 11:
253 goes into 1070 4 times with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 156176.814
The remainder is 58 after subtracting 1012 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
253 goes into 580 2 times with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 156176.8142
The remainder is 74 after subtracting 506 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
740 divided by 253 is 2 with a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 156176.81422
Subtract 506 from 740 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

After the division, we end up with 156176.81422 and a remainder of 0.000234.
