We're dividing 551464 by 91 
The aim is to understand the frequency of 91 in 551464.

Moving on to step 1:
91 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 91

Going ahead to step 2:
The number 91 fits into 55 0 times, leaving a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 91

Step 3:
91 goes into 551 6 times with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 5 after subtracting 546 from 551.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 91

Advancing to step 4:
When dividing 54 by 91, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 60.0
If we subtract 0 from 54, we get 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 91

Advancing to step 5:
When dividing 546 by 91, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 606.0
Subtracting 546 from 546 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 91

On to step 6:
91 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 6060.0
Subtract 0 from 4 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
91 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6060.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
91 goes into 400 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 6060.04
Deduct 364 from 400 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
When dividing 360 by 91, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 6060.043
Subtract 273 from 360 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 10:
The number 91 fits into 870 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 6060.0439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
When dividing 510 by 91, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6060.04395
If we take 455 away from 510, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 12:
The number 91 fits into 550 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6060.043956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 91, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 6060.043956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
91 goes into 400 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 6060.04395604
If we take 364 away from 400, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 6060.04395604 with a balance of 3.6e-08.
