We're dividing 71528620 by 884 
The aim is to understand the frequency of 884 in 71528620.

On to step 1:
884 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 884

Step 2:
The number 884 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 884

Step 3:
715 divided by 884 is 0 with a remainder of 715.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 715, we get 715.
Take the next digit (2) from the dividend and append it to 715, then repeat: 7152 / 884

Moving on to step 4:
When dividing 7152 by 884, we get 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7072 from 7152 leaves us with 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 884

Going ahead to step 5:
884 goes into 808 0 times with a remainder of 808.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 808 after subtracting 0 from 808.
Bring next digit (6) of the dividend behind the 808 and repeat the process: 8086 / 884

Going ahead to step 6:
If we divide 8086 by 884, we get 9 and a remainder of 130.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we subtract 7956 from 8086, we get 130.
Append the next digit (2) from the dividend to 130 and continue with: 1302 / 884

On to step 7:
884 can be fit into 1302 1 times, resulting in a remainder of 418.
Use 1 as the next digit of our solution. 
Result so far: 8091.0
If we subtract 884 from 1302, we get 418.
Append the next digit (0) from the dividend to 418 and continue with: 4180 / 884

Advancing to step 8:
The number 884 fits into 4180 4 times, leaving a remainder of 644.
Write down 4 as next digit of the result. 
Result so far: 80914.0
Deduct 3536 from 4180 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Step 9:
If we divide 6440 by 884, we get 7 and a remainder of 252.
The next digit of our result is 7. 
Result so far: 80914.7
If we take 6188 away from 6440, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 10:
The number 884 fits into 2520 2 times, leaving a remainder of 752.
Record the quotient 2 as the next digit in the result. 
Result so far: 80914.72
Deduct 1768 from 2520 and we're left with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 11:
884 goes into 7520 8 times with a remainder of 448.
Record the quotient 8 as the next digit in the result. 
Result so far: 80914.728
The remainder is 448 after subtracting 7072 from 7520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 12:
884 can be fit into 4480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 80914.7285
The remainder is 60 after subtracting 4420 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
600 divided by 884 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 80914.7285
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 14:
If we divide 6000 by 884, we get 6 and a remainder of 696.
Use 6 as the next digit of our solution. 
Result so far: 80914.728506
Subtracting 5304 from 6000 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 15:
The number 884 fits into 6960 7 times, leaving a remainder of 772.
Use 7 as the next digit of our solution. 
Result so far: 80914.7285067
If we subtract 6188 from 6960, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Moving on to step 16:
7720 divided by 884 is 8 with a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 80914.72850678
Deduct 7072 from 7720 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

The final outcome is 80914.72850678, with a leftover of 6.48e-07.
