We divide 39585379 by 172
We want to divide 39585379 by 172.

Moving on to step 1:
172 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 172

Going ahead to step 2:
39 divided by 172 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 172

On to step 3:
The number 172 fits into 395 2 times, leaving a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 344 from 395 leaves us with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 172

Going ahead to step 4:
When dividing 518 by 172, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 516 away from 518, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 172

Going ahead to step 5:
172 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 172

Advancing to step 6:
253 divided by 172 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 2301.0
The remainder is 81 after subtracting 172 from 253.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 172

Step 7:
817 divided by 172 is 4 with a remainder of 129.
Use 4 as the next digit of our solution. 
Result so far: 23014.0
If we take 688 away from 817, we end up with 129.
Include the next digit (9) from the dividend after 129, then repeat: 1299 / 172

On to step 8:
When dividing 1299 by 172, we get 7 with a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 230147.0
The remainder is 95 after subtracting 1204 from 1299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
If we divide 950 by 172, we get 5 and a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 230147.5
The remainder is 90 after subtracting 860 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 172 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 230147.55
If we subtract 860 from 900, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 230147.55 with a remainder of 0.04.
