We divide 6911872 by 243
The aim is to understand the frequency of 243 in 6911872.

On to step 1:
243 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 243

Advancing to step 2:
The number 243 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 243

Advancing to step 3:
If we divide 691 by 243, we get 2 and a remainder of 205.
The next digit of our result is 2. 
Result so far: 2.0
If we take 486 away from 691, we end up with 205.
Fetch the next digit (1) from the dividend, attach it to 205 and continue: 2051 / 243

Going ahead to step 4:
If we divide 2051 by 243, we get 8 and a remainder of 107.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 1944 from 2051 leaves us with 107.
Grab the next digit (8) from the dividend, add it to 107, then carry on: 1078 / 243

Let's proceed to step 5:
243 goes into 1078 4 times with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
If we subtract 972 from 1078, we get 106.
Bring next digit (7) of the dividend behind the 106 and repeat the process: 1067 / 243

Let's proceed to step 6:
243 can be fit into 1067 4 times, resulting in a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 2844.0
If we subtract 972 from 1067, we get 95.
Take the next digit (2) from the dividend and append it to 95, then repeat: 952 / 243

Let's proceed to step 7:
952 divided by 243 is 3 with a remainder of 223.
Record the quotient 3 as the next digit in the result. 
Result so far: 28443.0
If we take 729 away from 952, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 8:
When dividing 2230 by 243, we get 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 28443.9
Deduct 2187 from 2230 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
243 goes into 430 1 times with a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 28443.91
If we take 243 away from 430, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 10:
243 can be fit into 1870 7 times, resulting in a remainder of 169.
Use 7 as the next digit of our solution. 
Result so far: 28443.917
The remainder is 169 after subtracting 1701 from 1870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 11:
When dividing 1690 by 243, we get 6 with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 28443.9176
The remainder is 232 after subtracting 1458 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
2320 divided by 243 is 9 with a remainder of 133.
The next digit of our result is 9. 
Result so far: 28443.91769
Subtract 2187 from 2320 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 13:
The number 243 fits into 1330 5 times, leaving a remainder of 115.
The next digit of our result is 5. 
Result so far: 28443.917695
The remainder is 115 after subtracting 1215 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 14:
If we divide 1150 by 243, we get 4 and a remainder of 178.
The number 4 becomes the next digit in our result. 
Result so far: 28443.9176954
Subtract 972 from 1150 to get 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 15:
243 goes into 1780 7 times with a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 28443.91769547
The remainder is 79 after subtracting 1701 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final outcome is 28443.91769547, with a leftover of 7.9e-08.
