We look at the division of 91778138 by 884 
The aim is to understand the frequency of 884 in 91778138.

Moving on to step 1:
The number 884 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 884

Step 2:
The number 884 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 884

Moving on to step 3:
884 can be fit into 917 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 884 from 917 leaves us with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 884

Step 4:
If we divide 337 by 884, we get 0 and a remainder of 337.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 337 to get 337.
Fetch the next digit (8) from the dividend, attach it to 337 and continue: 3378 / 884

On to step 5:
884 can be fit into 3378 3 times, resulting in a remainder of 726.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 2652 from 3378, we get 726.
Bring next digit (1) of the dividend behind the 726 and repeat the process: 7261 / 884

Let's proceed to step 6:
7261 divided by 884 is 8 with a remainder of 189.
The number 8 becomes the next digit in our result. 
Result so far: 1038.0
Subtracting 7072 from 7261 leaves us with 189.
Append the next digit (3) from the dividend to 189 and continue with: 1893 / 884

Step 7:
The number 884 fits into 1893 2 times, leaving a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 10382.0
The remainder is 125 after subtracting 1768 from 1893.
Append the next digit (8) from the dividend to 125 and continue with: 1258 / 884

Advancing to step 8:
If we divide 1258 by 884, we get 1 and a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 103821.0
Deduct 884 from 1258 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 9:
3740 divided by 884 is 4 with a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 103821.4
Deduct 3536 from 3740 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 10:
When dividing 2040 by 884, we get 2 with a remainder of 272.
Use 2 as the next digit of our solution. 
Result so far: 103821.42
If we take 1768 away from 2040, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 11:
2720 divided by 884 is 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 103821.423
Deduct 2652 from 2720 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
When dividing 680 by 884, we get 0 with a remainder of 680.
The next digit of our result is 0. 
Result so far: 103821.423
If we subtract 0 from 680, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 13:
884 can be fit into 6800 7 times, resulting in a remainder of 612.
Write down 7 as next digit of the result. 
Result so far: 103821.42307
The remainder is 612 after subtracting 6188 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 14:
When dividing 6120 by 884, we get 6 with a remainder of 816.
Use 6 as the next digit of our solution. 
Result so far: 103821.423076
If we subtract 5304 from 6120, we get 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Going ahead to step 15:
884 can be fit into 8160 9 times, resulting in a remainder of 204.
Use 9 as the next digit of our solution. 
Result so far: 103821.4230769
Deduct 7956 from 8160 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 16:
When dividing 2040 by 884, we get 2 with a remainder of 272.
The next digit of our result is 2. 
Result so far: 103821.42307692
If we take 1768 away from 2040, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 103821.42307692, with a leftover of 2.72e-07.
