We divide 86852258 by 640
We want to figure out the number of times 86852258 can be divided by 640.

Advancing to step 1:
640 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 640

Going ahead to step 2:
When dividing 86 by 640, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 640

Step 3:
When dividing 868 by 640, we get 1 with a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 640 away from 868, we end up with 228.
Include the next digit (5) from the dividend after 228, then repeat: 2285 / 640

Let's proceed to step 4:
If we divide 2285 by 640, we get 3 and a remainder of 365.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 365 after subtracting 1920 from 2285.
Include the next digit (2) from the dividend after 365, then repeat: 3652 / 640

Let's proceed to step 5:
If we divide 3652 by 640, we get 5 and a remainder of 452.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 3200 from 3652 leaves us with 452.
Grab the next digit (2) from the dividend, add it to 452, then carry on: 4522 / 640

Advancing to step 6:
The number 640 fits into 4522 7 times, leaving a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 1357.0
If we take 4480 away from 4522, we end up with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 640

On to step 7:
If we divide 425 by 640, we get 0 and a remainder of 425.
Use 0 as the next digit of our solution. 
Result so far: 13570.0
The remainder is 425 after subtracting 0 from 425.
Bring next digit (8) of the dividend behind the 425 and repeat the process: 4258 / 640

Moving on to step 8:
When dividing 4258 by 640, we get 6 with a remainder of 418.
Use 6 as the next digit of our solution. 
Result so far: 135706.0
If we take 3840 away from 4258, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 9:
4180 divided by 640 is 6 with a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 135706.6
Deduct 3840 from 4180 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
The number 640 fits into 3400 5 times, leaving a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 135706.65
The remainder is 200 after subtracting 3200 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
If we divide 2000 by 640, we get 3 and a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 135706.653
If we subtract 1920 from 2000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 640, we get 1 with a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 135706.6531
The remainder is 160 after subtracting 640 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
1600 divided by 640 is 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 135706.65312
If we take 1280 away from 1600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 135706.653125
The remainder is 0 after subtracting 3200 from 3200.
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 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 135706.653125
Deduct 0 from 0 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.

Moving on to step 16:
640 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 135706.653125
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 outcome is 135706.653125, with a leftover of 0.0.
