We look at the division of 74629918 by 438 
The aim is to understand the frequency of 438 in 74629918.

Going ahead to step 1:
The number 438 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 438

Advancing to step 2:
If we divide 74 by 438, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 438

Advancing to step 3:
746 divided by 438 is 1 with a remainder of 308.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 438 from 746 and we're left with 308.
Take the next digit (2) from the dividend and append it to 308, then repeat: 3082 / 438

Moving on to step 4:
When dividing 3082 by 438, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 3066 from 3082 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 438

Step 5:
If we divide 169 by 438, we get 0 and a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 170.0
The remainder is 169 after subtracting 0 from 169.
Grab the next digit (9) from the dividend, add it to 169, then carry on: 1699 / 438

Going ahead to step 6:
If we divide 1699 by 438, we get 3 and a remainder of 385.
Use 3 as the next digit of our solution. 
Result so far: 1703.0
If we take 1314 away from 1699, we end up with 385.
Include the next digit (1) from the dividend after 385, then repeat: 3851 / 438

Going ahead to step 7:
The number 438 fits into 3851 8 times, leaving a remainder of 347.
Record the quotient 8 as the next digit in the result. 
Result so far: 17038.0
If we take 3504 away from 3851, we end up with 347.
Fetch the next digit (8) from the dividend, attach it to 347 and continue: 3478 / 438

Moving on to step 8:
The number 438 fits into 3478 7 times, leaving a remainder of 412.
Put 7 as the next digit of the answer. 
Result so far: 170387.0
Subtract 3066 from 3478 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
If we divide 4120 by 438, we get 9 and a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 170387.9
If we subtract 3942 from 4120, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
If we divide 1780 by 438, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 170387.94
If we subtract 1752 from 1780, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
The number 438 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 170387.94
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
If we divide 2800 by 438, we get 6 and a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 170387.9406
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 13:
If we divide 1720 by 438, we get 3 and a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 170387.94063
Deduct 1314 from 1720 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.

Moving on to step 14:
The number 438 fits into 4060 9 times, leaving a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 170387.940639
Subtract 3942 from 4060 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
If we divide 1180 by 438, we get 2 and a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 170387.9406392
If we subtract 876 from 1180, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 16:
When dividing 3040 by 438, we get 6 with a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 170387.94063926
If we subtract 2628 from 3040, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

In conclusion, the division gives 170387.94063926 with a balance of 4.12e-07.
