91497834 ÷ 880 
The aim is to understand the frequency of 880 in 91497834.

Going ahead to step 1:
The number 880 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 880

Moving on to step 2:
880 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 880

Moving on to step 3:
880 goes into 914 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 880 from 914 to get 34.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 880

Let's proceed to step 4:
880 goes into 349 0 times with a remainder of 349.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 349 to get 349.
Take the next digit (7) from the dividend and append it to 349, then repeat: 3497 / 880

Moving on to step 5:
If we divide 3497 by 880, we get 3 and a remainder of 857.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we subtract 2640 from 3497, we get 857.
Take the next digit (8) from the dividend and append it to 857, then repeat: 8578 / 880

Step 6:
If we divide 8578 by 880, we get 9 and a remainder of 658.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
If we take 7920 away from 8578, we end up with 658.
Fetch the next digit (3) from the dividend, attach it to 658 and continue: 6583 / 880

Step 7:
If we divide 6583 by 880, we get 7 and a remainder of 423.
Record the quotient 7 as the next digit in the result. 
Result so far: 10397.0
If we subtract 6160 from 6583, we get 423.
Include the next digit (4) from the dividend after 423, then repeat: 4234 / 880

Advancing to step 8:
If we divide 4234 by 880, we get 4 and a remainder of 714.
The next digit of our result is 4. 
Result so far: 103974.0
Subtract 3520 from 4234 to get 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

On to step 9:
7140 divided by 880 is 8 with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 103974.8
Deduct 7040 from 7140 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
1000 divided by 880 is 1 with a remainder of 120.
The next digit of our result is 1. 
Result so far: 103974.81
The remainder is 120 after subtracting 880 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
When dividing 1200 by 880, we get 1 with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 103974.811
If we take 880 away from 1200, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 103974.811 with a remainder of 0.032.
