We look at the division of 83833051 by 660 
We want to divide 83833051 by 660.

Step 1:
8 divided by 660 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 660

On to step 2:
660 goes into 83 0 times with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 660

Moving on to step 3:
838 divided by 660 is 1 with a remainder of 178.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 660 from 838 to get 178.
Append the next digit (3) from the dividend to 178 and continue with: 1783 / 660

Step 4:
When dividing 1783 by 660, we get 2 with a remainder of 463.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 463 after subtracting 1320 from 1783.
Take the next digit (3) from the dividend and append it to 463, then repeat: 4633 / 660

Moving on to step 5:
660 goes into 4633 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 127.0
Deduct 4620 from 4633 and we're left with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 660

Step 6:
660 can be fit into 130 0 times, resulting in a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 1270.0
The remainder is 130 after subtracting 0 from 130.
Fetch the next digit (5) from the dividend, attach it to 130 and continue: 1305 / 660

Step 7:
1305 divided by 660 is 1 with a remainder of 645.
Use 1 as the next digit of our solution. 
Result so far: 12701.0
Deduct 660 from 1305 and we're left with 645.
Append the next digit (1) from the dividend to 645 and continue with: 6451 / 660

Going ahead to step 8:
The number 660 fits into 6451 9 times, leaving a remainder of 511.
The number 9 becomes the next digit in our result. 
Result so far: 127019.0
If we take 5940 away from 6451, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 9:
If we divide 5110 by 660, we get 7 and a remainder of 490.
The number 7 becomes the next digit in our result. 
Result so far: 127019.7
If we take 4620 away from 5110, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
When dividing 4900 by 660, we get 7 with a remainder of 280.
Put 7 as the next digit of the answer. 
Result so far: 127019.77
The remainder is 280 after subtracting 4620 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 127019.77, with a leftover of 0.28.
