Let's divide 13821575 by 172
We want to figure out the number of times 13821575 can be divided by 172.

Moving on to step 1:
If we divide 1 by 172, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 172

Going ahead to step 2:
If we divide 13 by 172, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 172

On to step 3:
When dividing 138 by 172, we get 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 138, we get 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 172

Step 4:
The number 172 fits into 1382 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 1376 from 1382 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 172

Step 5:
172 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 61, we get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 172

Moving on to step 6:
If we divide 615 by 172, we get 3 and a remainder of 99.
The next digit of our result is 3. 
Result so far: 803.0
Subtract 516 from 615 to get 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 172

Going ahead to step 7:
If we divide 997 by 172, we get 5 and a remainder of 137.
The number 5 becomes the next digit in our result. 
Result so far: 8035.0
Subtracting 860 from 997 leaves us with 137.
Bring next digit (5) of the dividend behind the 137 and repeat the process: 1375 / 172

Going ahead to step 8:
1375 divided by 172 is 7 with a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 80357.0
The remainder is 171 after subtracting 1204 from 1375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 9:
If we divide 1710 by 172, we get 9 and a remainder of 162.
Write down 9 as next digit of the result. 
Result so far: 80357.9
The remainder is 162 after subtracting 1548 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 10:
172 goes into 1620 9 times with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 80357.99
If we take 1548 away from 1620, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 80357.99, and the remainder is 0.072.
