We divide 68691 by 90
Our goal is to divide 68691 by 90.

Step 1:
6 divided by 90 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 90

Moving on to step 2:
The number 90 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 90

Advancing to step 3:
90 goes into 686 7 times with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 630 away from 686, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 90

Step 4:
90 goes into 569 6 times with a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 540 from 569 to get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 90

On to step 5:
The number 90 fits into 291 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we subtract 270 from 291, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 6:
90 can be fit into 210 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 763.2
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 763.23
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 763.233
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 763.233 and a remainder of 0.003.
