We divide 43793309 by 221
The aim is to understand the frequency of 221 in 43793309.

Going ahead to step 1:
When dividing 4 by 221, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 221

Going ahead to step 2:
43 divided by 221 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 221

Going ahead to step 3:
If we divide 437 by 221, we get 1 and a remainder of 216.
The next digit of our result is 1. 
Result so far: 1.0
If we take 221 away from 437, we end up with 216.
Append the next digit (9) from the dividend to 216 and continue with: 2169 / 221

Step 4:
221 goes into 2169 9 times with a remainder of 180.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 1989 from 2169 to get 180.
Grab the next digit (3) from the dividend, add it to 180, then carry on: 1803 / 221

Advancing to step 5:
If we divide 1803 by 221, we get 8 and a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Subtract 1768 from 1803 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 221

Going ahead to step 6:
221 can be fit into 353 1 times, resulting in a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 1981.0
The remainder is 132 after subtracting 221 from 353.
Grab the next digit (0) from the dividend, add it to 132, then carry on: 1320 / 221

Advancing to step 7:
The number 221 fits into 1320 5 times, leaving a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 19815.0
Subtract 1105 from 1320 to get 215.
Grab the next digit (9) from the dividend, add it to 215, then carry on: 2159 / 221

On to step 8:
When dividing 2159 by 221, we get 9 with a remainder of 170.
Write down 9 as next digit of the result. 
Result so far: 198159.0
Subtract 1989 from 2159 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
221 can be fit into 1700 7 times, resulting in a remainder of 153.
The next digit of our result is 7. 
Result so far: 198159.7
If we take 1547 away from 1700, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 10:
1530 divided by 221 is 6 with a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 198159.76
If we subtract 1326 from 1530, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
2040 divided by 221 is 9 with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 198159.769
Deduct 1989 from 2040 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
221 goes into 510 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 198159.7692
Subtract 442 from 510 to 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.

Going ahead to step 13:
If we divide 680 by 221, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 198159.76923
The remainder is 17 after subtracting 663 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
When dividing 170 by 221, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 198159.76923
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 15:
221 can be fit into 1700 7 times, resulting in a remainder of 153.
The number 7 becomes the next digit in our result. 
Result so far: 198159.7692307
Subtracting 1547 from 1700 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 16:
221 can be fit into 1530 6 times, resulting in a remainder of 204.
The next digit of our result is 6. 
Result so far: 198159.76923076
If we subtract 1326 from 1530, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The quotient of the division is 198159.76923076, and the remainder is 2.04e-07.
