387889 divided by 91 
We're looking to find how many times 91 goes into 387889.

Going ahead to step 1:
91 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 91

Let's proceed to step 2:
91 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 91

Advancing to step 3:
When dividing 387 by 91, we get 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.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 91

Let's proceed to step 4:
If we divide 238 by 91, we get 2 and a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we take 182 away from 238, we end up with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 91

Let's proceed to step 5:
When dividing 568 by 91, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 426.0
Subtract 546 from 568 to get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 91

Let's proceed to step 6:
229 divided by 91 is 2 with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 4262.0
Deduct 182 from 229 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
If we divide 470 by 91, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 4262.5
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
91 goes into 150 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 4262.51
Subtracting 91 from 150 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
The number 91 fits into 590 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4262.516
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
91 can be fit into 440 4 times, resulting in a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4262.5164
Deduct 364 from 440 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.

Step 11:
760 divided by 91 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 4262.51648
If we take 728 away from 760, we end up 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.

Advancing to step 12:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4262.516483
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
When dividing 470 by 91, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 4262.5164835
Deduct 455 from 470 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
The number 91 fits into 150 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 4262.51648351
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

In conclusion, the division gives 4262.51648351 with a balance of 5.9e-08.
