We divide 513706 by 91
The aim is to understand the frequency of 91 in 513706.

Let's proceed to step 1:
5 divided by 91 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 91

Going ahead to step 2:
91 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 91

Advancing to step 3:
If we divide 513 by 91, we get 5 and a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 455 from 513 to get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 91

On to step 4:
When dividing 587 by 91, we get 6 with a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 546 from 587 to get 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 91

Going ahead to step 5:
The number 91 fits into 410 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 564.0
Subtract 364 from 410 to get 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 91

On to step 6:
When dividing 466 by 91, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5645.0
If we take 455 away from 466, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 91 fits into 110 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 5645.1
If we take 91 away from 110, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
When dividing 190 by 91, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5645.12
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 91 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 5645.12
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 91 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 5645.1208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
91 goes into 720 7 times with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 5645.12087
Deduct 637 from 720 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
830 divided by 91 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 5645.120879
Subtracting 819 from 830 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
91 can be fit into 110 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 5645.1208791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
If we divide 190 by 91, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 5645.12087912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 5645.12087912 with a balance of 8e-09.
