We divide 669452 by 90
We want to divide 669452 by 90.

Let's proceed to step 1:
90 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 90

On to step 2:
When dividing 66 by 90, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 90

Going ahead to step 3:
If we divide 669 by 90, we get 7 and a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 630 from 669, we get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 90

Let's proceed to step 4:
90 goes into 394 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 74.0
Deduct 360 from 394 and we're left with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 90

Step 5:
345 divided by 90 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 743.0
The remainder is 75 after subtracting 270 from 345.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 90

Going ahead to step 6:
90 can be fit into 752 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 7438.0
Subtracting 720 from 752 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 7438.3
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 90 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7438.35
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7438.355
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 7438.355 and a remainder of 0.005.
