We're dividing 99877632 by 172 
Our goal is to divide 99877632 by 172.

On to step 1:
9 divided by 172 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 172

Moving on to step 2:
172 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 172

Let's proceed to step 3:
172 goes into 998 5 times with a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 860 from 998 to get 138.
Fetch the next digit (7) from the dividend, attach it to 138 and continue: 1387 / 172

Going ahead to step 4:
1387 divided by 172 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 1376 from 1387 to get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 172

Step 5:
172 goes into 117 0 times with a remainder of 117.
Put 0 as the next digit of the answer. 
Result so far: 580.0
Subtracting 0 from 117 leaves us with 117.
Fetch the next digit (6) from the dividend, attach it to 117 and continue: 1176 / 172

On to step 6:
1176 divided by 172 is 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 5806.0
If we take 1032 away from 1176, we end up with 144.
Grab the next digit (3) from the dividend, add it to 144, then carry on: 1443 / 172

On to step 7:
The number 172 fits into 1443 8 times, leaving a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 58068.0
Deduct 1376 from 1443 and we're left with 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 172

Moving on to step 8:
If we divide 672 by 172, we get 3 and a remainder of 156.
The number 3 becomes the next digit in our result. 
Result so far: 580683.0
If we take 516 away from 672, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 9:
1560 divided by 172 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 580683.9
Subtract 1548 from 1560 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
If we divide 120 by 172, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 580683.9
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 172 is 6 with a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 580683.906
The remainder is 168 after subtracting 1032 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
When dividing 1680 by 172, we get 9 with a remainder of 132.
Write down 9 as next digit of the result. 
Result so far: 580683.9069
If we subtract 1548 from 1680, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 13:
The number 172 fits into 1320 7 times, leaving a remainder of 116.
The next digit of our result is 7. 
Result so far: 580683.90697
Subtract 1204 from 1320 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
172 can be fit into 1160 6 times, resulting in a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 580683.906976
If we subtract 1032 from 1160, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
1280 divided by 172 is 7 with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 580683.9069767
Subtracting 1204 from 1280 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 16:
172 can be fit into 760 4 times, resulting in a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 580683.90697674
If we take 688 away from 760, 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.

After the division, we end up with 580683.90697674 and a remainder of 7.2e-08.
