90780571 ÷ 964 
We want to figure out the number of times 90780571 can be divided by 964.

Let's proceed to step 1:
The number 964 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 964

Advancing to step 2:
90 divided by 964 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 964

Step 3:
The number 964 fits into 907 0 times, leaving a remainder of 907.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 907 after subtracting 0 from 907.
Fetch the next digit (8) from the dividend, attach it to 907 and continue: 9078 / 964

Moving on to step 4:
The number 964 fits into 9078 9 times, leaving a remainder of 402.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 402 after subtracting 8676 from 9078.
Grab the next digit (0) from the dividend, add it to 402, then carry on: 4020 / 964

Going ahead to step 5:
4020 divided by 964 is 4 with a remainder of 164.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 164 after subtracting 3856 from 4020.
Include the next digit (5) from the dividend after 164, then repeat: 1645 / 964

Going ahead to step 6:
1645 divided by 964 is 1 with a remainder of 681.
Put 1 as the next digit of the answer. 
Result so far: 941.0
Subtracting 964 from 1645 leaves us with 681.
Grab the next digit (7) from the dividend, add it to 681, then carry on: 6817 / 964

On to step 7:
When dividing 6817 by 964, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 9417.0
The remainder is 69 after subtracting 6748 from 6817.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 964

Moving on to step 8:
The number 964 fits into 691 0 times, leaving a remainder of 691.
Write down 0 as next digit of the result. 
Result so far: 94170.0
If we take 0 away from 691, we end up with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Step 9:
964 goes into 6910 7 times with a remainder of 162.
The next digit of our result is 7. 
Result so far: 94170.7
If we subtract 6748 from 6910, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
When dividing 1620 by 964, we get 1 with a remainder of 656.
Record the quotient 1 as the next digit in the result. 
Result so far: 94170.71
If we subtract 964 from 1620, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 11:
If we divide 6560 by 964, we get 6 and a remainder of 776.
Record the quotient 6 as the next digit in the result. 
Result so far: 94170.716
If we take 5784 away from 6560, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Going ahead to step 12:
964 goes into 7760 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 94170.7168
Subtract 7712 from 7760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
If we divide 480 by 964, we get 0 and a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 94170.7168
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
If we divide 4800 by 964, we get 4 and a remainder of 944.
The number 4 becomes the next digit in our result. 
Result so far: 94170.716804
Subtracting 3856 from 4800 leaves us with 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

Going ahead to step 15:
964 can be fit into 9440 9 times, resulting in a remainder of 764.
The next digit of our result is 9. 
Result so far: 94170.7168049
Subtracting 8676 from 9440 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 16:
964 goes into 7640 7 times with a remainder of 892.
The number 7 becomes the next digit in our result. 
Result so far: 94170.71680497
Deduct 6748 from 7640 and we're left with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

After the division, we end up with 94170.71680497 and a remainder of 8.92e-07.
