Let's divide 99310831 by 140
We want to divide 99310831 by 140.

Advancing to step 1:
The number 140 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 140

Going ahead to step 2:
99 divided by 140 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 140

Going ahead to step 3:
The number 140 fits into 993 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 980 from 993, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 140

On to step 4:
131 divided by 140 is 0 with a remainder of 131.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Subtract 0 from 131 to get 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 140

On to step 5:
1310 divided by 140 is 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 709.0
The remainder is 50 after subtracting 1260 from 1310.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 140

Going ahead to step 6:
When dividing 508 by 140, we get 3 with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 7093.0
The remainder is 88 after subtracting 420 from 508.
Include the next digit (3) from the dividend after 88, then repeat: 883 / 140

Advancing to step 7:
140 goes into 883 6 times with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 70936.0
The remainder is 43 after subtracting 840 from 883.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 140

Going ahead to step 8:
When dividing 431 by 140, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 709363.0
Deduct 420 from 431 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
The number 140 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 709363.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
When dividing 1100 by 140, we get 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 709363.07
If we subtract 980 from 1100, we 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.

On to step 11:
If we divide 1200 by 140, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 709363.078
If we subtract 1120 from 1200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
140 can be fit into 800 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 709363.0785
Subtracting 700 from 800 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
140 goes into 1000 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 709363.07857
The remainder is 20 after subtracting 980 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 140, we get 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 709363.078571
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
When dividing 600 by 140, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 709363.0785714
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 16:
400 divided by 140 is 2 with a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 709363.07857142
Subtract 280 from 400 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.

The final result is 709363.07857142 with a remainder of 1.2e-07.
