123567 ÷ 86 
We want to divide 123567 by 86.

Step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 86

On to step 2:
If we divide 12 by 86, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 86

Going ahead to step 3:
The number 86 fits into 123 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 86 from 123, we get 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 86

On to step 4:
If we divide 375 by 86, we get 4 and a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 344 away from 375, we end up with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 86

On to step 5:
The number 86 fits into 316 3 times, leaving a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 258 away from 316, we end up with 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 86

Advancing to step 6:
The number 86 fits into 587 6 times, leaving a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 1436.0
If we subtract 516 from 587, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
If we divide 710 by 86, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1436.8
Subtracting 688 from 710 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
86 goes into 220 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1436.82
Subtracting 172 from 220 leaves us 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 9:
When dividing 480 by 86, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1436.825
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.

On to step 10:
86 goes into 500 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 1436.8255
If we take 430 away from 500, we end up with 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 quotient of the division is 1436.8255, and the remainder is 0.0007.
