70469862 ÷ 90 
Our goal is to divide 70469862 by 90.

Moving on to step 1:
7 divided by 90 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 90

Step 2:
When dividing 70 by 90, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Bring next digit (4) of the dividend behind the 70 and repeat the process: 704 / 90

Advancing to step 3:
If we divide 704 by 90, we get 7 and a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 630 from 704 to get 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 90

Going ahead to step 4:
90 goes into 746 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 720 from 746, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 90

On to step 5:
90 goes into 269 2 times with a remainder of 89.
The next digit of our result is 2. 
Result so far: 782.0
If we take 180 away from 269, we end up with 89.
Include the next digit (8) from the dividend after 89, then repeat: 898 / 90

Moving on to step 6:
90 can be fit into 898 9 times, resulting in a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 7829.0
If we take 810 away from 898, we end up with 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 90

Let's proceed to step 7:
886 divided by 90 is 9 with a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 78299.0
If we take 810 away from 886, we end up with 76.
Grab the next digit (2) from the dividend, add it to 76, then carry on: 762 / 90

Moving on to step 8:
90 goes into 762 8 times with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 782998.0
If we subtract 720 from 762, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
If we divide 420 by 90, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 782998.4
If we take 360 away from 420, we end up 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 10:
90 goes into 600 6 times with a remainder of 60.
The next digit of our result is 6. 
Result so far: 782998.46
If we subtract 540 from 600, we get 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 11:
90 goes into 600 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 782998.466
Subtract 540 from 600 to get 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 782998.466, and the remainder is 0.006.
