685066 ÷ 90 
Let's see how many times 90 fits into 685066.

On to step 1:
90 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 90

Moving on to step 2:
68 divided by 90 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 90

Moving on to step 3:
When dividing 685 by 90, we get 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 630 from 685 and we're left with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 90

Going ahead to step 4:
550 divided by 90 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we take 540 away from 550, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 90

On to step 5:
When dividing 106 by 90, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 761.0
Deduct 90 from 106 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 90

Advancing to step 6:
90 goes into 166 1 times with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 7611.0
If we subtract 90 from 166, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
If we divide 760 by 90, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 7611.8
Subtract 720 from 760 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 7611.84
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 7611.844
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 7611.844 and a remainder of 0.004.
