We divide 771294 by 90
Let's see how many times 90 fits into 771294.

Going ahead to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 90

Going ahead to step 2:
77 divided by 90 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 90

Let's proceed to step 3:
90 can be fit into 771 8 times, resulting in a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 720 from 771 and we're left with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 90

On to step 4:
90 goes into 512 5 times with a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 450 away from 512, we end up with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 90

Let's proceed to step 5:
When dividing 629 by 90, we get 6 with a remainder of 89.
Use 6 as the next digit of our solution. 
Result so far: 856.0
Deduct 540 from 629 and we're left with 89.
Include the next digit (4) from the dividend after 89, then repeat: 894 / 90

Step 6:
If we divide 894 by 90, we get 9 and a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 8569.0
Deduct 810 from 894 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
If we divide 840 by 90, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 8569.9
The remainder is 30 after subtracting 810 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 8569.93
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 8569.933
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 8569.933, with a leftover of 0.003.
