We're dividing 64035381 by 86 
We want to divide 64035381 by 86.

On to step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 86

Moving on to step 2:
When dividing 64 by 86, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 86

Advancing to step 3:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 602 from 640 and we're left with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 86

On to step 4:
When dividing 383 by 86, we get 4 with a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 344 from 383 leaves us with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 86

Moving on to step 5:
395 divided by 86 is 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 744.0
Subtracting 344 from 395 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 86

Step 6:
If we divide 513 by 86, we get 5 and a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 7445.0
If we subtract 430 from 513, we get 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 86

Advancing to step 7:
When dividing 838 by 86, we get 9 with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 74459.0
The remainder is 64 after subtracting 774 from 838.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 86

Moving on to step 8:
The number 86 fits into 641 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 744597.0
Subtract 602 from 641 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
86 can be fit into 390 4 times, resulting in a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 744597.4
The remainder is 46 after subtracting 344 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
460 divided by 86 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 744597.45
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 744597.453
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 744597.4534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
If we divide 760 by 86, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 744597.45348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 744597.453488
Subtracting 688 from 720 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.

The final result is 744597.453488 with a remainder of 3.2e-06.
