We divide 70939585 by 90
We want to figure out the number of times 70939585 can be divided by 90.

Let's proceed to step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 90

Step 2:
90 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 90

Let's proceed to step 3:
90 goes into 709 7 times with a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 630 from 709 to get 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 90

On to step 4:
90 goes into 793 8 times with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 720 away from 793, we end up with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 90

Step 5:
The number 90 fits into 739 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 788.0
Subtracting 720 from 739 leaves us with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 90

Advancing to step 6:
90 goes into 195 2 times with a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 7882.0
The remainder is 15 after subtracting 180 from 195.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 90

Advancing to step 7:
When dividing 158 by 90, we get 1 with a remainder of 68.
The next digit of our result is 1. 
Result so far: 78821.0
Subtract 90 from 158 to get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 90

Moving on to step 8:
685 divided by 90 is 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 788217.0
If we take 630 away from 685, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
90 can be fit into 550 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 788217.6
Subtract 540 from 550 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
90 goes into 100 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 788217.61
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 90, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 788217.611
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 788217.611, and the remainder is 0.001.
