We look at the division of 85377878 by 64 
We want to figure out the number of times 85377878 can be divided by 64.

Advancing to step 1:
64 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 64

Moving on to step 2:
64 goes into 85 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 64 from 85, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 64

Let's proceed to step 3:
The number 64 fits into 213 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 192 away from 213, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 64

Advancing to step 4:
If we divide 217 by 64, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
The remainder is 25 after subtracting 192 from 217.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 64

On to step 5:
The number 64 fits into 257 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 1334.0
If we subtract 256 from 257, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 64

Step 6:
When dividing 18 by 64, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 13340.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 64

On to step 7:
64 goes into 187 2 times with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 133402.0
Deduct 128 from 187 and we're left with 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 64

On to step 8:
598 divided by 64 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1334029.0
If we take 576 away from 598, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
If we divide 220 by 64, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1334029.3
Subtracting 192 from 220 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 64 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 1334029.34
Subtract 256 from 280 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.

Moving on to step 11:
The number 64 fits into 240 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1334029.343
If we take 192 away from 240, we end up 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.

Moving on to step 12:
480 divided by 64 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 1334029.3437
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on 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: 1334029.34375
The remainder is 0 after subtracting 320 from 320.
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:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1334029.34375
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.

Moving on 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: 1334029.34375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1334029.34375 with a remaining 0.0.
