We divide 731388 by 86
Let's see how many times 86 fits into 731388.

On to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 86

Let's proceed to step 2:
86 can be fit into 73 0 times, resulting in a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (1) from the dividend and append it to 73, then repeat: 731 / 86

Advancing to step 3:
86 goes into 731 8 times with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 43 after subtracting 688 from 731.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 86

Moving on to step 4:
The number 86 fits into 433 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 430 from 433 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 86

Advancing to step 5:
86 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 86

Going ahead to step 6:
86 goes into 388 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 8504.0
Subtracting 344 from 388 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 8504.5
Subtracting 430 from 440 leaves us 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.

On to step 8:
If we divide 100 by 86, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 8504.51
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 8504.511
If we subtract 86 from 140, we 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.

After the division, we end up with 8504.511 and a remainder of 0.0054.
