We divide 780013 by 90
We're looking to find how many times 90 goes into 780013.

Going ahead to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 90

Going ahead to step 2:
When dividing 78 by 90, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 90

On to step 3:
When dividing 780 by 90, we get 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 720 from 780 to get 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 90

Let's proceed to step 4:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 540 from 600 and we're left with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 90

On to step 5:
90 goes into 601 6 times with a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 866.0
If we take 540 away from 601, we end up with 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 90

Let's proceed to step 6:
If we divide 613 by 90, we get 6 and a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 8666.0
The remainder is 73 after subtracting 540 from 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
90 can be fit into 730 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 8666.8
If we subtract 720 from 730, 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.

Let's proceed to step 8:
100 divided by 90 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 8666.81
Subtracting 90 from 100 leaves us 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.

Moving on to step 9:
If we divide 100 by 90, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 8666.811
Subtracting 90 from 100 leaves us 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.

After the division, we end up with 8666.811 and a remainder of 0.001.
