We look at the division of 71988313 by 884 
The aim is to understand the frequency of 884 in 71988313.

Advancing to step 1:
The number 884 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 884

On to step 2:
884 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 884

Moving on to step 3:
When dividing 719 by 884, we get 0 with a remainder of 719.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 719, we end up with 719.
Append the next digit (8) from the dividend to 719 and continue with: 7198 / 884

Advancing to step 4:
When dividing 7198 by 884, we get 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7072 from 7198 to get 126.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 884

Advancing to step 5:
If we divide 1268 by 884, we get 1 and a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 884 from 1268, we get 384.
Fetch the next digit (3) from the dividend, attach it to 384 and continue: 3843 / 884

On to step 6:
The number 884 fits into 3843 4 times, leaving a remainder of 307.
The next digit of our result is 4. 
Result so far: 814.0
Deduct 3536 from 3843 and we're left with 307.
Take the next digit (1) from the dividend and append it to 307, then repeat: 3071 / 884

On to step 7:
884 goes into 3071 3 times with a remainder of 419.
Record the quotient 3 as the next digit in the result. 
Result so far: 8143.0
Deduct 2652 from 3071 and we're left with 419.
Append the next digit (3) from the dividend to 419 and continue with: 4193 / 884

Advancing to step 8:
If we divide 4193 by 884, we get 4 and a remainder of 657.
The next digit of our result is 4. 
Result so far: 81434.0
If we take 3536 away from 4193, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 9:
884 can be fit into 6570 7 times, resulting in a remainder of 382.
Use 7 as the next digit of our solution. 
Result so far: 81434.7
Deduct 6188 from 6570 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
3820 divided by 884 is 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 81434.74
The remainder is 284 after subtracting 3536 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
884 can be fit into 2840 3 times, resulting in a remainder of 188.
Put 3 as the next digit of the answer. 
Result so far: 81434.743
Subtract 2652 from 2840 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 12:
1880 divided by 884 is 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 81434.7432
Deduct 1768 from 1880 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 13:
If we divide 1120 by 884, we get 1 and a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 81434.74321
The remainder is 236 after subtracting 884 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 14:
If we divide 2360 by 884, we get 2 and a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 81434.743212
Subtracting 1768 from 2360 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 15:
If we divide 5920 by 884, we get 6 and a remainder of 616.
The number 6 becomes the next digit in our result. 
Result so far: 81434.7432126
Subtract 5304 from 5920 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Moving on to step 16:
The number 884 fits into 6160 6 times, leaving a remainder of 856.
Put 6 as the next digit of the answer. 
Result so far: 81434.74321266
Subtracting 5304 from 6160 leaves us with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

The final result is 81434.74321266 with a remainder of 8.56e-07.
