We're dividing 63448 by 91 
The aim is to understand the frequency of 91 in 63448.

Going ahead to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 91

Let's proceed to step 2:
The number 91 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 91

Advancing to step 3:
91 can be fit into 634 6 times, resulting in a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 546 from 634 and we're left with 88.
Take the next digit (4) from the dividend and append it to 88, then repeat: 884 / 91

Step 4:
91 can be fit into 884 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtract 819 from 884 to get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 91

Let's proceed to step 5:
658 divided by 91 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 697.0
Subtract 637 from 658 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 6:
If we divide 210 by 91, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 697.2
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
91 goes into 280 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 697.23
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
70 divided by 91 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 697.23
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
91 can be fit into 700 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 697.2307
Subtracting 637 from 700 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
When dividing 630 by 91, we get 6 with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 697.23076
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
When dividing 840 by 91, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 697.230769
Deduct 819 from 840 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 91 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 697.2307692
Subtract 182 from 210 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
91 goes into 280 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 697.23076923
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 697.23076923 with a balance of 7e-09.
