Let's divide 37745343 by 86
We want to figure out the number of times 37745343 can be divided by 86.

On to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 86

On to step 2:
37 divided by 86 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 86

Going ahead to step 3:
377 divided by 86 is 4 with a remainder of 33.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 344 from 377 to get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 86

Step 4:
334 divided by 86 is 3 with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 258 from 334 to get 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 86

Going ahead to step 5:
86 can be fit into 765 8 times, resulting in a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 438.0
The remainder is 77 after subtracting 688 from 765.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 86

Going ahead to step 6:
86 can be fit into 773 8 times, resulting in a remainder of 85.
The next digit of our result is 8. 
Result so far: 4388.0
Deduct 688 from 773 and we're left with 85.
Include the next digit (4) from the dividend after 85, then repeat: 854 / 86

Advancing to step 7:
86 goes into 854 9 times with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 43889.0
If we take 774 away from 854, we end up with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 86

Step 8:
86 goes into 803 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 438899.0
Subtracting 774 from 803 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 86, we get 3 and a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 438899.3
Subtract 258 from 290 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.

Step 10:
When dividing 320 by 86, we get 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 438899.33
Subtracting 258 from 320 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 438899.33, and the remainder is 0.062.
