Let's divide 89001422 by 64
We want to divide 89001422 by 64.

Step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 64

Step 2:
If we divide 89 by 64, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 64 from 89 to get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 64

On to step 3:
The number 64 fits into 250 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 192 from 250 to get 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 64

On to step 4:
64 goes into 580 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we subtract 576 from 580, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 64

Moving on to step 5:
64 goes into 41 0 times with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 1390.0
Subtract 0 from 41 to get 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 64

Advancing to step 6:
When dividing 414 by 64, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 13906.0
If we subtract 384 from 414, we get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 64

On to step 7:
64 goes into 302 4 times with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 139064.0
The remainder is 46 after subtracting 256 from 302.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 64

Step 8:
When dividing 462 by 64, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 1390647.0
If we take 448 away from 462, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 64 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 1390647.2
If we subtract 128 from 140, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 64 is 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 1390647.21
If we subtract 64 from 120, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
560 divided by 64 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1390647.218
Deduct 512 from 560 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
When dividing 480 by 64, we get 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1390647.2187
Subtracting 448 from 480 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.

Advancing to step 13:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 1390647.21875
Subtracting 320 from 320 leaves us 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.

Let's proceed to step 14:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1390647.21875
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.

Going ahead to step 15:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1390647.21875
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.

The final outcome is 1390647.21875, with a leftover of 0.0.
