We look at the division of 18115814 by 847 
The aim is to understand the frequency of 847 in 18115814.

Moving on to step 1:
The number 847 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 847

On to step 2:
If we divide 18 by 847, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 847

Step 3:
181 divided by 847 is 0 with a remainder of 181.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Take the next digit (1) from the dividend and append it to 181, then repeat: 1811 / 847

Advancing to step 4:
847 goes into 1811 2 times with a remainder of 117.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1694 from 1811 leaves us with 117.
Grab the next digit (5) from the dividend, add it to 117, then carry on: 1175 / 847

On to step 5:
847 goes into 1175 1 times with a remainder of 328.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 847 from 1175 to get 328.
Grab the next digit (8) from the dividend, add it to 328, then carry on: 3288 / 847

Moving on to step 6:
When dividing 3288 by 847, we get 3 with a remainder of 747.
Write down 3 as next digit of the result. 
Result so far: 213.0
Deduct 2541 from 3288 and we're left with 747.
Append the next digit (1) from the dividend to 747 and continue with: 7471 / 847

Moving on to step 7:
847 goes into 7471 8 times with a remainder of 695.
Write down 8 as next digit of the result. 
Result so far: 2138.0
Deduct 6776 from 7471 and we're left with 695.
Fetch the next digit (4) from the dividend, attach it to 695 and continue: 6954 / 847

Let's proceed to step 8:
The number 847 fits into 6954 8 times, leaving a remainder of 178.
The next digit of our result is 8. 
Result so far: 21388.0
Subtracting 6776 from 6954 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 9:
When dividing 1780 by 847, we get 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 21388.2
Deduct 1694 from 1780 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
If we divide 860 by 847, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 21388.21
If we subtract 847 from 860, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
When dividing 130 by 847, we get 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 21388.21
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
847 can be fit into 1300 1 times, resulting in a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 21388.2101
If we subtract 847 from 1300, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 13:
If we divide 4530 by 847, we get 5 and a remainder of 295.
The next digit of our result is 5. 
Result so far: 21388.21015
Subtract 4235 from 4530 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 14:
When dividing 2950 by 847, we get 3 with a remainder of 409.
Write down 3 as next digit of the result. 
Result so far: 21388.210153
Deduct 2541 from 2950 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 15:
847 can be fit into 4090 4 times, resulting in a remainder of 702.
Record the quotient 4 as the next digit in the result. 
Result so far: 21388.2101534
The remainder is 702 after subtracting 3388 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Let's proceed to step 16:
847 goes into 7020 8 times with a remainder of 244.
Put 8 as the next digit of the answer. 
Result so far: 21388.21015348
Subtracting 6776 from 7020 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 21388.21015348 with a remainder of 2.44e-07.
