We divide 670692 by 90
Let's see how many times 90 fits into 670692.

Advancing to step 1:
90 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 90

Going ahead to step 2:
The number 90 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Fetch the next digit (0) from the dividend, attach it to 67 and continue: 670 / 90

Let's proceed to step 3:
90 goes into 670 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 630 from 670, we get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 90

Advancing to step 4:
90 goes into 406 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 46 after subtracting 360 from 406.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 90

Moving on to step 5:
If we divide 469 by 90, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 745.0
Deduct 450 from 469 and we're left with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 90

Going ahead to step 6:
The number 90 fits into 192 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 7452.0
Subtract 180 from 192 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 90, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 7452.1
If we take 90 away from 120, we end up 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.

Let's proceed to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 7452.13
Subtracting 270 from 300 leaves us 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 9:
90 goes into 300 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 7452.133
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.

The final result is 7452.133 with a remainder of 0.003.
