Let's divide 99286190 by 129
Our goal is to divide 99286190 by 129.

Advancing to step 1:
9 divided by 129 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.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 129

On to step 2:
If we divide 99 by 129, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 129

Going ahead to step 3:
129 can be fit into 992 7 times, resulting in a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 903 from 992 and we're left with 89.
Take the next digit (8) from the dividend and append it to 89, then repeat: 898 / 129

Going ahead to step 4:
If we divide 898 by 129, we get 6 and a remainder of 124.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 774 from 898 leaves us with 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 129

Advancing to step 5:
When dividing 1246 by 129, we get 9 with a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
The remainder is 85 after subtracting 1161 from 1246.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 129

On to step 6:
129 goes into 851 6 times with a remainder of 77.
The next digit of our result is 6. 
Result so far: 7696.0
Subtracting 774 from 851 leaves us with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 129

Step 7:
If we divide 779 by 129, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 76966.0
Subtracting 774 from 779 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 129

Step 8:
50 divided by 129 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 769660.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
129 can be fit into 500 3 times, resulting in a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 769660.3
The remainder is 113 after subtracting 387 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 10:
If we divide 1130 by 129, we get 8 and a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 769660.38
Deduct 1032 from 1130 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 11:
When dividing 980 by 129, we get 7 with a remainder of 77.
The next digit of our result is 7. 
Result so far: 769660.387
The remainder is 77 after subtracting 903 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
770 divided by 129 is 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 769660.3875
Deduct 645 from 770 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 13:
129 can be fit into 1250 9 times, resulting in a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 769660.38759
Subtracting 1161 from 1250 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 14:
129 can be fit into 890 6 times, resulting in a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 769660.387596
The remainder is 116 after subtracting 774 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 15:
If we divide 1160 by 129, we get 8 and a remainder of 128.
The next digit of our result is 8. 
Result so far: 769660.3875968
Deduct 1032 from 1160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 16:
1280 divided by 129 is 9 with a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 769660.38759689
Subtract 1161 from 1280 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

After the division, we end up with 769660.38759689 and a remainder of 1.19e-07.
