We're dividing 661102 by 86 
Let's see how many times 86 fits into 661102.

Moving on to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 86

Moving on to step 2:
66 divided by 86 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 86

Moving on to step 3:
86 goes into 661 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 59 after subtracting 602 from 661.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 86

Step 4:
591 divided by 86 is 6 with a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 75 after subtracting 516 from 591.
Grab the next digit (0) from the dividend, add it to 75, then carry on: 750 / 86

Advancing to step 5:
When dividing 750 by 86, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 768.0
The remainder is 62 after subtracting 688 from 750.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 86

Advancing to step 6:
The number 86 fits into 622 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7687.0
Subtracting 602 from 622 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
86 goes into 200 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7687.2
If we take 172 away from 200, we end up 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.

Moving on to step 8:
When dividing 280 by 86, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 7687.23
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 86, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 7687.232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
86 goes into 480 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7687.2325
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 7687.23255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 7687.23255 with a remainder of 7e-05.
