We divide 69039860 by 90
Let's see how many times 90 fits into 69039860.

Going ahead to step 1:
90 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 90

Let's proceed to step 2:
When dividing 69 by 90, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 90

Advancing to step 3:
90 can be fit into 690 7 times, resulting in a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 630 from 690 to get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 90

Step 4:
90 can be fit into 603 6 times, resulting in a remainder of 63.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 63 after subtracting 540 from 603.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 90

Going ahead to step 5:
639 divided by 90 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
Subtract 630 from 639 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 90

On to step 6:
The number 90 fits into 98 1 times, leaving a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 7671.0
Deduct 90 from 98 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 90

Let's proceed to step 7:
When dividing 86 by 90, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 76710.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 90

Going ahead to step 8:
The number 90 fits into 860 9 times, leaving a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 767109.0
Subtract 810 from 860 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.

Let's proceed to step 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 767109.5
Subtracting 450 from 500 leaves us 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.

Moving on to step 10:
90 can be fit into 500 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 767109.55
If we subtract 450 from 500, we 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.

Our division results in 767109.55 with a remaining 0.05.
