69999347 ÷ 90 
We're looking to find how many times 90 goes into 69999347.

Advancing to step 1:
The number 90 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 90

Going ahead to step 2:
69 divided by 90 is 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 90

Advancing to step 3:
699 divided by 90 is 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 630 from 699 and we're left with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 90

Let's proceed to step 4:
The number 90 fits into 699 7 times, leaving a remainder of 69.
The next digit of our result is 7. 
Result so far: 77.0
Subtract 630 from 699 to get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 90

Advancing to step 5:
When dividing 699 by 90, we get 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 777.0
If we subtract 630 from 699, we get 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 90

Going ahead to step 6:
When dividing 693 by 90, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 7777.0
The remainder is 63 after subtracting 630 from 693.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 90

Step 7:
634 divided by 90 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 77777.0
If we subtract 630 from 634, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 90

On to step 8:
The number 90 fits into 47 0 times, leaving a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 777770.0
If we take 0 away from 47, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
If we divide 470 by 90, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 777770.5
The remainder is 20 after subtracting 450 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 777770.52
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 777770.522
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 777770.522 with a balance of 0.002.
