Let's divide 459678 by 91
The aim is to understand the frequency of 91 in 459678.

Step 1:
91 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 91

On to step 2:
If we divide 45 by 91, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 91

Moving on to step 3:
The number 91 fits into 459 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 4 after subtracting 455 from 459.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 91

Advancing to step 4:
91 goes into 46 0 times with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 46, we get 46.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 91

On to step 5:
When dividing 467 by 91, we get 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 505.0
The remainder is 12 after subtracting 455 from 467.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 91

Moving on to step 6:
91 goes into 128 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 5051.0
Subtract 91 from 128 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
When dividing 370 by 91, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 5051.4
Subtracting 364 from 370 leaves us 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 8:
91 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5051.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 91 fits into 600 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 5051.406
If we subtract 546 from 600, we 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.

On to step 10:
If we divide 540 by 91, we get 5 and a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 5051.4065
Subtract 455 from 540 to get 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 11:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 5051.40659
The remainder is 31 after subtracting 819 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
91 can be fit into 310 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 5051.406593
If we take 273 away from 310, we end up 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.

Let's proceed to step 13:
91 can be fit into 370 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5051.4065934
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.

Advancing to step 14:
When dividing 60 by 91, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5051.4065934
If we take 0 away from 60, we end up 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.

In conclusion, the division gives 5051.4065934 with a balance of 6e-08.
