We're dividing 74744051 by 438 
The aim is to understand the frequency of 438 in 74744051.

Advancing to step 1:
The number 438 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 438

On to step 2:
438 goes into 74 0 times with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 438

On to step 3:
If we divide 747 by 438, we get 1 and a remainder of 309.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 309 after subtracting 438 from 747.
Grab the next digit (4) from the dividend, add it to 309, then carry on: 3094 / 438

Let's proceed to step 4:
When dividing 3094 by 438, we get 7 with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 3066 from 3094, we get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 438

Advancing to step 5:
If we divide 284 by 438, we get 0 and a remainder of 284.
The next digit of our result is 0. 
Result so far: 170.0
If we take 0 away from 284, we end up with 284.
Bring next digit (0) of the dividend behind the 284 and repeat the process: 2840 / 438

Step 6:
The number 438 fits into 2840 6 times, leaving a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 1706.0
Subtract 2628 from 2840 to get 212.
Grab the next digit (5) from the dividend, add it to 212, then carry on: 2125 / 438

Moving on to step 7:
When dividing 2125 by 438, we get 4 with a remainder of 373.
Record the quotient 4 as the next digit in the result. 
Result so far: 17064.0
Subtracting 1752 from 2125 leaves us with 373.
Bring next digit (1) of the dividend behind the 373 and repeat the process: 3731 / 438

Step 8:
The number 438 fits into 3731 8 times, leaving a remainder of 227.
Write down 8 as next digit of the result. 
Result so far: 170648.0
Subtract 3504 from 3731 to get 227.
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:
The number 438 fits into 2270 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 170648.5
If we subtract 2190 from 2270, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 438 is 1 with a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 170648.51
Subtract 438 from 800 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 11:
3620 divided by 438 is 8 with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 170648.518
Deduct 3504 from 3620 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 12:
438 goes into 1160 2 times with a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 170648.5182
If we subtract 876 from 1160, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 13:
2840 divided by 438 is 6 with a remainder of 212.
The next digit of our result is 6. 
Result so far: 170648.51826
If we take 2628 away from 2840, 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 14:
If we divide 2120 by 438, we get 4 and a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 170648.518264
If we take 1752 away from 2120, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 15:
438 can be fit into 3680 8 times, resulting in a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 170648.5182648
If we take 3504 away from 3680, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 16:
438 can be fit into 1760 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 170648.51826484
Subtract 1752 from 1760 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 170648.51826484 with a balance of 8e-09.
