Let's divide 68983509 by 851
Our goal is to divide 68983509 by 851.

Advancing to step 1:
851 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 851

Going ahead to step 2:
When dividing 68 by 851, we get 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 851

On to step 3:
When dividing 689 by 851, we get 0 with a remainder of 689.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 689 to get 689.
Bring next digit (8) of the dividend behind the 689 and repeat the process: 6898 / 851

Step 4:
When dividing 6898 by 851, we get 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6808 from 6898 leaves us with 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 851

Going ahead to step 5:
If we divide 903 by 851, we get 1 and a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 851 away from 903, we end up with 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 851

Going ahead to step 6:
The number 851 fits into 525 0 times, leaving a remainder of 525.
Write down 0 as next digit of the result. 
Result so far: 810.0
Deduct 0 from 525 and we're left with 525.
Bring next digit (0) of the dividend behind the 525 and repeat the process: 5250 / 851

Moving on to step 7:
When dividing 5250 by 851, we get 6 with a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 8106.0
The remainder is 144 after subtracting 5106 from 5250.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 851

Step 8:
851 can be fit into 1449 1 times, resulting in a remainder of 598.
Put 1 as the next digit of the answer. 
Result so far: 81061.0
Subtract 851 from 1449 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 9:
5980 divided by 851 is 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 81061.7
Deduct 5957 from 5980 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
230 divided by 851 is 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 81061.7
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
851 can be fit into 2300 2 times, resulting in a remainder of 598.
Write down 2 as next digit of the result. 
Result so far: 81061.702
Subtracting 1702 from 2300 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 12:
If we divide 5980 by 851, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 81061.7027
If we take 5957 away from 5980, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
851 goes into 230 0 times with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 81061.7027
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
If we divide 2300 by 851, we get 2 and a remainder of 598.
The next digit of our result is 2. 
Result so far: 81061.702702
If we subtract 1702 from 2300, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 15:
851 goes into 5980 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 81061.7027027
If we subtract 5957 from 5980, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 16:
If we divide 230 by 851, we get 0 and a remainder of 230.
The next digit of our result is 0. 
Result so far: 81061.7027027
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 81061.7027027, with a leftover of 2.3e-07.
