Let's divide 28176291 by 129
We want to figure out the number of times 28176291 can be divided by 129.

Going ahead to step 1:
129 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 129

Going ahead to step 2:
The number 129 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 129

Advancing to step 3:
129 can be fit into 281 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 258 away from 281, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 129

Step 4:
If we divide 237 by 129, we get 1 and a remainder of 108.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 108 after subtracting 129 from 237.
Fetch the next digit (6) from the dividend, attach it to 108 and continue: 1086 / 129

On to step 5:
1086 divided by 129 is 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
If we take 1032 away from 1086, we end up with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 129

Advancing to step 6:
When dividing 542 by 129, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2184.0
If we subtract 516 from 542, we get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 129

Moving on to step 7:
129 can be fit into 269 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 21842.0
Subtract 258 from 269 to get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 129

On to step 8:
The number 129 fits into 111 0 times, leaving a remainder of 111.
Write down 0 as next digit of the result. 
Result so far: 218420.0
Subtracting 0 from 111 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 9:
If we divide 1110 by 129, we get 8 and a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 218420.8
Deduct 1032 from 1110 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
780 divided by 129 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 218420.86
If we take 774 away from 780, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
129 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 218420.86
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
When dividing 600 by 129, we get 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 218420.8604
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
When dividing 840 by 129, we get 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 218420.86046
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
129 goes into 660 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 218420.860465
If we take 645 away from 660, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
The number 129 fits into 150 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 218420.8604651
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
If we divide 210 by 129, we get 1 and a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 218420.86046511
If we take 129 away from 210, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final result is 218420.86046511 with a remainder of 8.1e-08.
