Let's divide 76640087 by 64
Our goal is to divide 76640087 by 64.

Advancing to step 1:
If we divide 7 by 64, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 64

Let's proceed to step 2:
If we divide 76 by 64, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 64 from 76 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 64

Step 3:
64 goes into 126 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 64 from 126 to get 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 64

Let's proceed to step 4:
624 divided by 64 is 9 with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 119.0
The remainder is 48 after subtracting 576 from 624.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 64

On to step 5:
When dividing 480 by 64, we get 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we subtract 448 from 480, we get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 64

Going ahead to step 6:
64 goes into 320 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11975.0
If we take 320 away from 320, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 64

Advancing to step 7:
When dividing 8 by 64, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 119750.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 64

Moving on to step 8:
87 divided by 64 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1197501.0
The remainder is 23 after subtracting 64 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
When dividing 230 by 64, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1197501.3
The remainder is 38 after subtracting 192 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 64 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1197501.35
Subtracting 320 from 380 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 1197501.359
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 64, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 1197501.3593
Subtract 192 from 240 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.

Let's proceed to step 13:
The number 64 fits into 480 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1197501.35937
Deduct 448 from 480 and we're left 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.

Step 14:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1197501.359375
Deduct 320 from 320 and we're left 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.

Going ahead to step 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1197501.359375
If we take 0 away from 0, 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.

Step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1197501.359375
Subtracting 0 from 0 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.

The final result is 1197501.359375 with a remainder of 0.0.
