Let's divide 388806 by 91
Our goal is to divide 388806 by 91.

Going ahead to step 1:
If we divide 3 by 91, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 91

On to step 2:
91 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 91

On to step 3:
If we divide 388 by 91, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 24 after subtracting 364 from 388.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 91

On to step 4:
248 divided by 91 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we take 182 away from 248, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 91

Let's proceed to step 5:
660 divided by 91 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 427.0
If we subtract 637 from 660, we get 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 91

Advancing to step 6:
The number 91 fits into 236 2 times, leaving a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 4272.0
Subtracting 182 from 236 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
91 can be fit into 540 5 times, resulting in a remainder of 85.
The next digit of our result is 5. 
Result so far: 4272.5
Subtracting 455 from 540 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 8:
If we divide 850 by 91, we get 9 and a remainder of 31.
The next digit of our result is 9. 
Result so far: 4272.59
If we take 819 away from 850, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
If we divide 310 by 91, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 4272.593
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
370 divided by 91 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4272.5934
If we take 364 away from 370, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 91 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4272.5934
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 91, we get 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 4272.593406
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
91 goes into 540 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 4272.5934065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 14:
850 divided by 91 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 4272.59340659
Subtracting 819 from 850 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 4272.59340659 with a remainder of 3.1e-08.
