We look at the division of 863737 by 90 
Our goal is to divide 863737 by 90.

Advancing to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 90

Let's proceed to step 2:
86 divided by 90 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 90

On to step 3:
If we divide 863 by 90, we get 9 and a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 810 from 863, we get 53.
Bring next digit (7) of the dividend behind the 53 and repeat the process: 537 / 90

Moving on to step 4:
When dividing 537 by 90, we get 5 with a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 450 from 537 and we're left with 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 90

Moving on to step 5:
873 divided by 90 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 959.0
Subtracting 810 from 873 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 90

Step 6:
90 goes into 637 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 9597.0
Subtract 630 from 637 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 90 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 9597.0
If we take 0 away from 70, 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.

Advancing to step 8:
90 goes into 700 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 9597.07
Deduct 630 from 700 and we're left 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.

Moving on to step 9:
When dividing 700 by 90, we get 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 9597.077
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 9597.077 with a remaining 0.007.
