Let's divide 43576349 by 337
The aim is to understand the frequency of 337 in 43576349.

Going ahead to step 1:
If we divide 4 by 337, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 337

Going ahead to step 2:
The number 337 fits into 43 0 times, leaving a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 337

Going ahead to step 3:
435 divided by 337 is 1 with a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 337 from 435 leaves us with 98.
Bring next digit (7) of the dividend behind the 98 and repeat the process: 987 / 337

On to step 4:
337 can be fit into 987 2 times, resulting in a remainder of 313.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 313 after subtracting 674 from 987.
Grab the next digit (6) from the dividend, add it to 313, then carry on: 3136 / 337

Step 5:
If we divide 3136 by 337, we get 9 and a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 3033 from 3136 to get 103.
Take the next digit (3) from the dividend and append it to 103, then repeat: 1033 / 337

Going ahead to step 6:
The number 337 fits into 1033 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 1293.0
If we subtract 1011 from 1033, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 337

Advancing to step 7:
When dividing 224 by 337, we get 0 with a remainder of 224.
Record the quotient 0 as the next digit in the result. 
Result so far: 12930.0
Deduct 0 from 224 and we're left with 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 337

On to step 8:
337 goes into 2249 6 times with a remainder of 227.
Write down 6 as next digit of the result. 
Result so far: 129306.0
The remainder is 227 after subtracting 2022 from 2249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 9:
337 goes into 2270 6 times with a remainder of 248.
The next digit of our result is 6. 
Result so far: 129306.6
If we take 2022 away from 2270, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
The number 337 fits into 2480 7 times, leaving a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 129306.67
Subtracting 2359 from 2480 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 11:
1210 divided by 337 is 3 with a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 129306.673
The remainder is 199 after subtracting 1011 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 12:
337 can be fit into 1990 5 times, resulting in a remainder of 305.
The next digit of our result is 5. 
Result so far: 129306.6735
If we subtract 1685 from 1990, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 13:
337 goes into 3050 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 129306.67359
If we take 3033 away from 3050, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
When dividing 170 by 337, we get 0 with a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 129306.67359
Subtract 0 from 170 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.

Let's proceed to step 15:
1700 divided by 337 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 129306.6735905
Subtracting 1685 from 1700 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
When dividing 150 by 337, we get 0 with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 129306.6735905
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 129306.6735905 with a remainder of 1.5e-07.
