661131 ÷ 83 
We want to figure out the number of times 661131 can be divided by 83.

On to step 1:
If we divide 6 by 83, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 83

On to step 2:
66 divided by 83 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 83

Going ahead to step 3:
83 goes into 661 7 times with a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 581 from 661 and we're left with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 83

Advancing to step 4:
If we divide 801 by 83, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 747 from 801 leaves us with 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 83

Step 5:
83 can be fit into 543 6 times, resulting in a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 796.0
The remainder is 45 after subtracting 498 from 543.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 83

On to step 6:
If we divide 451 by 83, we get 5 and a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 7965.0
Subtract 415 from 451 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 83 fits into 360 4 times, leaving a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 7965.4
Deduct 332 from 360 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
If we divide 280 by 83, we get 3 and a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 7965.43
The remainder is 31 after subtracting 249 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 83 fits into 310 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 7965.433
If we take 249 away from 310, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The quotient of the division is 7965.433, and the remainder is 0.0061.
