89661364 divided by 64 
Our goal is to divide 89661364 by 64.

Going ahead to step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 64

Moving on to step 2:
64 goes into 89 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we take 64 away from 89, we end up with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 64

Let's proceed to step 3:
The number 64 fits into 256 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 256 from 256 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 64

Moving on to step 4:
64 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 64

Advancing to step 5:
When dividing 61 by 64, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 1400.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 64

Moving on to step 6:
The number 64 fits into 613 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 14009.0
The remainder is 37 after subtracting 576 from 613.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 64

Going ahead to step 7:
376 divided by 64 is 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 140095.0
If we subtract 320 from 376, we get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 64

Going ahead to step 8:
The number 64 fits into 564 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1400958.0
Subtract 512 from 564 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 64 fits into 520 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1400958.8
If we subtract 512 from 520, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 64, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1400958.81
If we take 64 away from 80, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1400958.812
Subtracting 128 from 160 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1400958.8125
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1400958.8125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1400958.8125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1400958.8125, with a leftover of 0.0.
