We're dividing 43752565 by 849 
The aim is to understand the frequency of 849 in 43752565.

Advancing to step 1:
849 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 849

Moving on to step 2:
849 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 849

Going ahead to step 3:
The number 849 fits into 437 0 times, leaving a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 437 leaves us with 437.
Bring next digit (5) of the dividend behind the 437 and repeat the process: 4375 / 849

Moving on to step 4:
4375 divided by 849 is 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4245 away from 4375, we end up with 130.
Bring next digit (2) of the dividend behind the 130 and repeat the process: 1302 / 849

On to step 5:
The number 849 fits into 1302 1 times, leaving a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 453 after subtracting 849 from 1302.
Bring next digit (5) of the dividend behind the 453 and repeat the process: 4535 / 849

On to step 6:
If we divide 4535 by 849, we get 5 and a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 515.0
If we take 4245 away from 4535, we end up with 290.
Append the next digit (6) from the dividend to 290 and continue with: 2906 / 849

Going ahead to step 7:
If we divide 2906 by 849, we get 3 and a remainder of 359.
Write down 3 as next digit of the result. 
Result so far: 5153.0
Deduct 2547 from 2906 and we're left with 359.
Grab the next digit (5) from the dividend, add it to 359, then carry on: 3595 / 849

Going ahead to step 8:
3595 divided by 849 is 4 with a remainder of 199.
Put 4 as the next digit of the answer. 
Result so far: 51534.0
Subtract 3396 from 3595 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 9:
849 goes into 1990 2 times with a remainder of 292.
Record the quotient 2 as the next digit in the result. 
Result so far: 51534.2
If we subtract 1698 from 1990, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 10:
If we divide 2920 by 849, we get 3 and a remainder of 373.
Write down 3 as next digit of the result. 
Result so far: 51534.23
If we take 2547 away from 2920, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 11:
849 can be fit into 3730 4 times, resulting in a remainder of 334.
The next digit of our result is 4. 
Result so far: 51534.234
Subtract 3396 from 3730 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 12:
If we divide 3340 by 849, we get 3 and a remainder of 793.
The next digit of our result is 3. 
Result so far: 51534.2343
The remainder is 793 after subtracting 2547 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Moving on to step 13:
If we divide 7930 by 849, we get 9 and a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 51534.23439
If we take 7641 away from 7930, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 14:
849 can be fit into 2890 3 times, resulting in a remainder of 343.
Record the quotient 3 as the next digit in the result. 
Result so far: 51534.234393
Subtracting 2547 from 2890 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 15:
849 goes into 3430 4 times with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 51534.2343934
The remainder is 34 after subtracting 3396 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
If we divide 340 by 849, we get 0 and a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 51534.2343934
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

In conclusion, the division gives 51534.2343934 with a balance of 3.4e-07.
