91225708 ÷ 441 
The aim is to understand the frequency of 441 in 91225708.

On to step 1:
If we divide 9 by 441, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 441

On to step 2:
If we divide 91 by 441, we get 0 and a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (2) of the dividend behind the 91 and repeat the process: 912 / 441

Let's proceed to step 3:
The number 441 fits into 912 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 30 after subtracting 882 from 912.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 441

Advancing to step 4:
441 can be fit into 302 0 times, resulting in a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 302, we get 302.
Take the next digit (5) from the dividend and append it to 302, then repeat: 3025 / 441

Advancing to step 5:
441 can be fit into 3025 6 times, resulting in a remainder of 379.
Write down 6 as next digit of the result. 
Result so far: 206.0
The remainder is 379 after subtracting 2646 from 3025.
Bring next digit (7) of the dividend behind the 379 and repeat the process: 3797 / 441

Advancing to step 6:
441 goes into 3797 8 times with a remainder of 269.
The next digit of our result is 8. 
Result so far: 2068.0
Deduct 3528 from 3797 and we're left with 269.
Fetch the next digit (0) from the dividend, attach it to 269 and continue: 2690 / 441

Advancing to step 7:
The number 441 fits into 2690 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 20686.0
The remainder is 44 after subtracting 2646 from 2690.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 441

Step 8:
448 divided by 441 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 206861.0
Deduct 441 from 448 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 441 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 206861.0
If we take 0 away from 70, we end up 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.

On to step 10:
441 can be fit into 700 1 times, resulting in a remainder of 259.
The next digit of our result is 1. 
Result so far: 206861.01
If we take 441 away from 700, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 11:
The number 441 fits into 2590 5 times, leaving a remainder of 385.
The number 5 becomes the next digit in our result. 
Result so far: 206861.015
Deduct 2205 from 2590 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 12:
If we divide 3850 by 441, we get 8 and a remainder of 322.
Put 8 as the next digit of the answer. 
Result so far: 206861.0158
If we subtract 3528 from 3850, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 13:
When dividing 3220 by 441, we get 7 with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 206861.01587
The remainder is 133 after subtracting 3087 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 14:
If we divide 1330 by 441, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 206861.015873
If we take 1323 away from 1330, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 15:
70 divided by 441 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 206861.015873
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
If we divide 700 by 441, we get 1 and a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 206861.01587301
Deduct 441 from 700 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

In conclusion, the division gives 206861.01587301 with a balance of 2.59e-07.
