We look at the division of 387307 by 91 
Let's see how many times 91 fits into 387307.

On to step 1:
When dividing 3 by 91, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 91

Step 2:
38 divided by 91 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 91

On to step 3:
387 divided by 91 is 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 364 from 387, we get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 91

Let's proceed to step 4:
91 goes into 233 2 times with a remainder of 51.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 182 from 233 and we're left with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 91

Going ahead to step 5:
510 divided by 91 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 425.0
Deduct 455 from 510 and we're left with 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 91

Moving on to step 6:
557 divided by 91 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 4256.0
Deduct 546 from 557 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 91, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 4256.1
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
91 can be fit into 190 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4256.12
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
80 divided by 91 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 4256.12
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
91 goes into 800 8 times with a remainder of 72.
The next digit of our result is 8. 
Result so far: 4256.1208
Deduct 728 from 800 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.

Step 11:
If we divide 720 by 91, we get 7 and a remainder of 83.
The number 7 becomes the next digit in our result. 
Result so far: 4256.12087
If we subtract 637 from 720, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 12:
91 can be fit into 830 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4256.120879
Deduct 819 from 830 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
If we divide 110 by 91, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4256.1208791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
If we divide 190 by 91, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 4256.12087912
Subtracting 182 from 190 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 4256.12087912 with a remaining 8e-09.
