84238109 ÷ 247 
The aim is to understand the frequency of 247 in 84238109.

On to step 1:
If we divide 8 by 247, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 247

Moving on to step 2:
If we divide 84 by 247, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 247

On to step 3:
247 goes into 842 3 times with a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 741 from 842 leaves us with 101.
Bring next digit (3) of the dividend behind the 101 and repeat the process: 1013 / 247

Step 4:
The number 247 fits into 1013 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 988 from 1013 to get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 247

Moving on to step 5:
247 can be fit into 258 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 341.0
Deduct 247 from 258 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 247

Advancing to step 6:
247 goes into 111 0 times with a remainder of 111.
The next digit of our result is 0. 
Result so far: 3410.0
Subtract 0 from 111 to get 111.
Grab the next digit (0) from the dividend, add it to 111, then carry on: 1110 / 247

Step 7:
1110 divided by 247 is 4 with a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 34104.0
If we subtract 988 from 1110, we get 122.
Append the next digit (9) from the dividend to 122 and continue with: 1229 / 247

On to step 8:
The number 247 fits into 1229 4 times, leaving a remainder of 241.
Write down 4 as next digit of the result. 
Result so far: 341044.0
If we subtract 988 from 1229, we get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 9:
2410 divided by 247 is 9 with a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 341044.9
The remainder is 187 after subtracting 2223 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 10:
247 goes into 1870 7 times with a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 341044.97
Subtracting 1729 from 1870 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 11:
247 goes into 1410 5 times with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 341044.975
If we take 1235 away from 1410, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
1750 divided by 247 is 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 341044.9757
Deduct 1729 from 1750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
210 divided by 247 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 341044.9757
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
2100 divided by 247 is 8 with a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 341044.975708
The remainder is 124 after subtracting 1976 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 15:
If we divide 1240 by 247, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 341044.9757085
The remainder is 5 after subtracting 1235 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
50 divided by 247 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 341044.9757085
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 341044.9757085, with a leftover of 5e-08.
