We're dividing 29393272 by 438 
The aim is to understand the frequency of 438 in 29393272.

Let's proceed to step 1:
The number 438 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 438

Advancing to step 2:
When dividing 29 by 438, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 438

Moving on to step 3:
438 goes into 293 0 times with a remainder of 293.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 293 after subtracting 0 from 293.
Append the next digit (9) from the dividend to 293 and continue with: 2939 / 438

On to step 4:
If we divide 2939 by 438, we get 6 and a remainder of 311.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 2628 from 2939, we get 311.
Include the next digit (3) from the dividend after 311, then repeat: 3113 / 438

Advancing to step 5:
If we divide 3113 by 438, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 3066 from 3113, we get 47.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 438

Advancing to step 6:
472 divided by 438 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 671.0
Deduct 438 from 472 and we're left with 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 438

Advancing to step 7:
When dividing 347 by 438, we get 0 with a remainder of 347.
Record the quotient 0 as the next digit in the result. 
Result so far: 6710.0
Deduct 0 from 347 and we're left with 347.
Grab the next digit (2) from the dividend, add it to 347, then carry on: 3472 / 438

Step 8:
3472 divided by 438 is 7 with a remainder of 406.
Use 7 as the next digit of our solution. 
Result so far: 67107.0
Deduct 3066 from 3472 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 9:
When dividing 4060 by 438, we get 9 with a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 67107.9
The remainder is 118 after subtracting 3942 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 10:
438 can be fit into 1180 2 times, resulting in a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 67107.92
Deduct 876 from 1180 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 11:
If we divide 3040 by 438, we get 6 and a remainder of 412.
The next digit of our result is 6. 
Result so far: 67107.926
Deduct 2628 from 3040 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 12:
438 can be fit into 4120 9 times, resulting in a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 67107.9269
The remainder is 178 after subtracting 3942 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 13:
When dividing 1780 by 438, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 67107.92694
Deduct 1752 from 1780 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
280 divided by 438 is 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 67107.92694
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
When dividing 2800 by 438, we get 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 67107.9269406
The remainder is 172 after subtracting 2628 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 16:
438 goes into 1720 3 times with a remainder of 406.
Write down 3 as next digit of the result. 
Result so far: 67107.92694063
Subtract 1314 from 1720 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The quotient of the division is 67107.92694063, and the remainder is 4.06e-07.
