We look at the division of 86973889 by 847 
The aim is to understand the frequency of 847 in 86973889.

Step 1:
The number 847 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 847

Step 2:
86 divided by 847 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 847

Going ahead to step 3:
847 goes into 869 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 847 away from 869, we end up with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 847

On to step 4:
847 goes into 227 0 times with a remainder of 227.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 227 leaves us with 227.
Append the next digit (3) from the dividend to 227 and continue with: 2273 / 847

Let's proceed to step 5:
847 can be fit into 2273 2 times, resulting in a remainder of 579.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 579 after subtracting 1694 from 2273.
Fetch the next digit (8) from the dividend, attach it to 579 and continue: 5798 / 847

Going ahead to step 6:
The number 847 fits into 5798 6 times, leaving a remainder of 716.
The number 6 becomes the next digit in our result. 
Result so far: 1026.0
The remainder is 716 after subtracting 5082 from 5798.
Grab the next digit (8) from the dividend, add it to 716, then carry on: 7168 / 847

Let's proceed to step 7:
If we divide 7168 by 847, we get 8 and a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 10268.0
If we take 6776 away from 7168, we end up with 392.
Append the next digit (9) from the dividend to 392 and continue with: 3929 / 847

Let's proceed to step 8:
3929 divided by 847 is 4 with a remainder of 541.
Use 4 as the next digit of our solution. 
Result so far: 102684.0
Subtract 3388 from 3929 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 9:
When dividing 5410 by 847, we get 6 with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 102684.6
Subtract 5082 from 5410 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 10:
If we divide 3280 by 847, we get 3 and a remainder of 739.
Record the quotient 3 as the next digit in the result. 
Result so far: 102684.63
If we take 2541 away from 3280, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Going ahead to step 11:
847 can be fit into 7390 8 times, resulting in a remainder of 614.
The number 8 becomes the next digit in our result. 
Result so far: 102684.638
Deduct 6776 from 7390 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 12:
847 can be fit into 6140 7 times, resulting in a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 102684.6387
Subtract 5929 from 6140 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 13:
If we divide 2110 by 847, we get 2 and a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 102684.63872
If we subtract 1694 from 2110, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 14:
If we divide 4160 by 847, we get 4 and a remainder of 772.
Put 4 as the next digit of the answer. 
Result so far: 102684.638724
If we subtract 3388 from 4160, 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.

Step 15:
If we divide 7720 by 847, we get 9 and a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 102684.6387249
Subtracting 7623 from 7720 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 16:
970 divided by 847 is 1 with a remainder of 123.
The next digit of our result is 1. 
Result so far: 102684.63872491
If we take 847 away from 970, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

After the division, we end up with 102684.63872491 and a remainder of 1.23e-07.
