We're dividing 4438945 by 542 
The aim is to understand the frequency of 542 in 4438945.

Going ahead to step 1:
4 divided by 542 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 542

Advancing to step 2:
542 can be fit into 44 0 times, resulting in a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 542

On to step 3:
When dividing 443 by 542, we get 0 with a remainder of 443.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 443 and we're left with 443.
Grab the next digit (8) from the dividend, add it to 443, then carry on: 4438 / 542

Moving on to step 4:
When dividing 4438 by 542, we get 8 with a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 4336 from 4438 leaves us with 102.
Fetch the next digit (9) from the dividend, attach it to 102 and continue: 1029 / 542

Moving on to step 5:
If we divide 1029 by 542, we get 1 and a remainder of 487.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 487 after subtracting 542 from 1029.
Bring next digit (4) of the dividend behind the 487 and repeat the process: 4874 / 542

Moving on to step 6:
542 goes into 4874 8 times with a remainder of 538.
The next digit of our result is 8. 
Result so far: 818.0
If we subtract 4336 from 4874, we get 538.
Fetch the next digit (5) from the dividend, attach it to 538 and continue: 5385 / 542

Advancing to step 7:
542 goes into 5385 9 times with a remainder of 507.
Record the quotient 9 as the next digit in the result. 
Result so far: 8189.0
If we subtract 4878 from 5385, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 8:
When dividing 5070 by 542, we get 9 with a remainder of 192.
Put 9 as the next digit of the answer. 
Result so far: 8189.9
The remainder is 192 after subtracting 4878 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 9:
542 goes into 1920 3 times with a remainder of 294.
Use 3 as the next digit of our solution. 
Result so far: 8189.93
Subtracting 1626 from 1920 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 10:
542 goes into 2940 5 times with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 8189.935
Subtracting 2710 from 2940 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
542 goes into 2300 4 times with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 8189.9354
The remainder is 132 after subtracting 2168 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
542 can be fit into 1320 2 times, resulting in a remainder of 236.
The next digit of our result is 2. 
Result so far: 8189.93542
Deduct 1084 from 1320 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 13:
542 goes into 2360 4 times with a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 8189.935424
Deduct 2168 from 2360 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
When dividing 1920 by 542, we get 3 with a remainder of 294.
Put 3 as the next digit of the answer. 
Result so far: 8189.9354243
Deduct 1626 from 1920 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 15:
When dividing 2940 by 542, we get 5 with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 8189.93542435
The remainder is 230 after subtracting 2710 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

In conclusion, the division gives 8189.93542435 with a balance of 2.3e-07.
