478128 divided by 91 
We want to figure out the number of times 478128 can be divided by 91.

Let's proceed to step 1:
The number 91 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 91

Step 2:
If we divide 47 by 91, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 91

On to step 3:
The number 91 fits into 478 5 times, leaving a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 455 from 478 leaves us with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 91

Let's proceed to step 4:
The number 91 fits into 231 2 times, leaving a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 182 away from 231, we end up with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 91

Advancing to step 5:
When dividing 492 by 91, we get 5 with a remainder of 37.
The next digit of our result is 5. 
Result so far: 525.0
Subtract 455 from 492 to get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 91

Moving on to step 6:
378 divided by 91 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 5254.0
If we take 364 away from 378, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
91 goes into 140 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 5254.1
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 8:
If we divide 490 by 91, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5254.15
If we subtract 455 from 490, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
91 goes into 350 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 5254.153
If we subtract 273 from 350, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 10:
When dividing 770 by 91, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 5254.1538
Deduct 728 from 770 and we're left 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 11:
420 divided by 91 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5254.15384
Subtracting 364 from 420 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
560 divided by 91 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 5254.153846
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 91, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 5254.1538461
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
91 goes into 490 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5254.15384615
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 5254.15384615 with a balance of 3.5e-08.
