We divide 670065 by 90
We want to figure out the number of times 670065 can be divided by 90.

Moving on to step 1:
When dividing 6 by 90, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 90

Advancing to step 2:
90 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 90

Let's proceed to step 3:
90 can be fit into 670 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 630 from 670 leaves us with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 90

Step 4:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 40 after subtracting 360 from 400.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 90

Advancing to step 5:
If we divide 406 by 90, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 744.0
Subtracting 360 from 406 leaves us with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 90

On to step 6:
465 divided by 90 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 7445.0
Deduct 450 from 465 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
90 can be fit into 150 1 times, resulting in a remainder of 60.
The next digit of our result is 1. 
Result so far: 7445.1
Deduct 90 from 150 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 7445.16
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 7445.166
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 7445.166, and the remainder is 0.006.
