We're dividing 69661 by 86 
We want to divide 69661 by 86.

On to step 1:
6 divided by 86 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 86

Step 2:
If we divide 69 by 86, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 86

Advancing to step 3:
86 goes into 696 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 688 from 696 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 86

Moving on to step 4:
When dividing 86 by 86, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 86 from 86 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 86

Step 5:
If we divide 1 by 86, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 810.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 6:
If we divide 10 by 86, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 810.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 86, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 810.01
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 86, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 810.011
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 810.011, and the remainder is 0.0054.
