We divide 672979 by 90
We're looking to find how many times 90 goes into 672979.

Step 1:
6 divided by 90 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 90

Going ahead to step 2:
If we divide 67 by 90, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 90

Step 3:
When dividing 672 by 90, we get 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 630 from 672, we get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 90

Let's proceed to step 4:
If we divide 429 by 90, we get 4 and a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 360 away from 429, we end up with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 90

Step 5:
When dividing 697 by 90, we get 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 747.0
Deduct 630 from 697 and we're left with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 90

Moving on to step 6:
90 can be fit into 679 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 7477.0
Subtracting 630 from 679 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
90 can be fit into 490 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 7477.5
Subtracting 450 from 490 leaves us 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.

Going ahead to step 8:
90 goes into 400 4 times with a remainder of 40.
The next digit of our result is 4. 
Result so far: 7477.54
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.

Step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 7477.544
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.

After the division, we end up with 7477.544 and a remainder of 0.004.
