We're dividing 599341 by 91 
The aim is to understand the frequency of 91 in 599341.

Going ahead to step 1:
The number 91 fits into 5 0 times, leaving 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.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 91

Let's proceed to step 2:
If we divide 59 by 91, we get 0 and a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 91

Step 3:
If we divide 599 by 91, we get 6 and a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 546 away from 599, we end up with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 91

On to step 4:
If we divide 533 by 91, we get 5 and a remainder of 78.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
The remainder is 78 after subtracting 455 from 533.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 91

Step 5:
91 goes into 784 8 times with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 658.0
If we take 728 away from 784, we end up with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 91

Advancing to step 6:
If we divide 561 by 91, we get 6 and a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 6586.0
The remainder is 15 after subtracting 546 from 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 91 fits into 150 1 times, leaving a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 6586.1
If we subtract 91 from 150, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
91 can be fit into 590 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6586.16
The remainder is 44 after subtracting 546 from 590.
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 9:
When dividing 440 by 91, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 6586.164
If we take 364 away from 440, we end up 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.

Let's proceed to step 10:
When dividing 760 by 91, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 6586.1648
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 11:
The number 91 fits into 320 3 times, leaving a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 6586.16483
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
The number 91 fits into 470 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6586.164835
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.

On to step 13:
When dividing 150 by 91, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 6586.1648351
The remainder is 59 after subtracting 91 from 150.
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 14:
590 divided by 91 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6586.16483516
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.

In conclusion, the division gives 6586.16483516 with a balance of 4.4e-08.
