Let's divide 39120737 by 243
The aim is to understand the frequency of 243 in 39120737.

Going ahead to step 1:
243 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 243

Step 2:
If we divide 39 by 243, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 243

On to step 3:
243 goes into 391 1 times with a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 148 after subtracting 243 from 391.
Append the next digit (2) from the dividend to 148 and continue with: 1482 / 243

Step 4:
When dividing 1482 by 243, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 1458 from 1482, we get 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 243

Going ahead to step 5:
If we divide 240 by 243, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 160.0
Subtract 0 from 240 to get 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 243

Let's proceed to step 6:
2407 divided by 243 is 9 with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 1609.0
Deduct 2187 from 2407 and we're left with 220.
Grab the next digit (3) from the dividend, add it to 220, then carry on: 2203 / 243

Let's proceed to step 7:
When dividing 2203 by 243, we get 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 16099.0
Subtract 2187 from 2203 to get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 243

Advancing to step 8:
243 can be fit into 167 0 times, resulting in a remainder of 167.
The next digit of our result is 0. 
Result so far: 160990.0
Subtracting 0 from 167 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 9:
243 goes into 1670 6 times with a remainder of 212.
The next digit of our result is 6. 
Result so far: 160990.6
If we take 1458 away from 1670, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
If we divide 2120 by 243, we get 8 and a remainder of 176.
The next digit of our result is 8. 
Result so far: 160990.68
The remainder is 176 after subtracting 1944 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 11:
1760 divided by 243 is 7 with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 160990.687
If we take 1701 away from 1760, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 12:
If we divide 590 by 243, we get 2 and a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 160990.6872
If we take 486 away from 590, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 13:
If we divide 1040 by 243, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 160990.68724
If we subtract 972 from 1040, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
680 divided by 243 is 2 with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 160990.687242
Subtracting 486 from 680 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 15:
When dividing 1940 by 243, we get 7 with a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 160990.6872427
Deduct 1701 from 1940 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 16:
When dividing 2390 by 243, we get 9 with a remainder of 203.
The number 9 becomes the next digit in our result. 
Result so far: 160990.68724279
The remainder is 203 after subtracting 2187 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Our division results in 160990.68724279 with a remaining 2.03e-07.
