91049429 divided by 874 
The aim is to understand the frequency of 874 in 91049429.

Going ahead to step 1:
When dividing 9 by 874, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 874

On to step 2:
If we divide 91 by 874, we get 0 and a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 874

Going ahead to step 3:
874 can be fit into 910 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 36 after subtracting 874 from 910.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 874

Moving on to step 4:
874 can be fit into 364 0 times, resulting in a remainder of 364.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 364, we end up with 364.
Fetch the next digit (9) from the dividend, attach it to 364 and continue: 3649 / 874

Advancing to step 5:
874 goes into 3649 4 times with a remainder of 153.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 3496 from 3649, we get 153.
Grab the next digit (4) from the dividend, add it to 153, then carry on: 1534 / 874

Let's proceed to step 6:
874 can be fit into 1534 1 times, resulting in a remainder of 660.
Record the quotient 1 as the next digit in the result. 
Result so far: 1041.0
If we take 874 away from 1534, we end up with 660.
Append the next digit (2) from the dividend to 660 and continue with: 6602 / 874

Going ahead to step 7:
874 can be fit into 6602 7 times, resulting in a remainder of 484.
The next digit of our result is 7. 
Result so far: 10417.0
The remainder is 484 after subtracting 6118 from 6602.
Bring next digit (9) of the dividend behind the 484 and repeat the process: 4849 / 874

Moving on to step 8:
When dividing 4849 by 874, we get 5 with a remainder of 479.
The next digit of our result is 5. 
Result so far: 104175.0
Subtract 4370 from 4849 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
874 goes into 4790 5 times with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 104175.5
If we take 4370 away from 4790, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
874 goes into 4200 4 times with a remainder of 704.
Put 4 as the next digit of the answer. 
Result so far: 104175.54
Subtracting 3496 from 4200 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 11:
7040 divided by 874 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 104175.548
If we take 6992 away from 7040, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 874, we get 0 and a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 104175.548
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
When dividing 4800 by 874, we get 5 with a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 104175.54805
Subtract 4370 from 4800 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 14:
When dividing 4300 by 874, we get 4 with a remainder of 804.
Record the quotient 4 as the next digit in the result. 
Result so far: 104175.548054
Subtract 3496 from 4300 to get 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Advancing to step 15:
When dividing 8040 by 874, we get 9 with a remainder of 174.
Record the quotient 9 as the next digit in the result. 
Result so far: 104175.5480549
If we take 7866 away from 8040, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
If we divide 1740 by 874, we get 1 and a remainder of 866.
The next digit of our result is 1. 
Result so far: 104175.54805491
Subtract 874 from 1740 to get 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

The final outcome is 104175.54805491, with a leftover of 8.66e-07.
