Let's divide 1607744 by 438
The aim is to understand the frequency of 438 in 1607744.

Let's proceed to step 1:
The number 438 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 438

Advancing to step 2:
16 divided by 438 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 438

Step 3:
160 divided by 438 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 160 and we're left with 160.
Bring next digit (7) of the dividend behind the 160 and repeat the process: 1607 / 438

Moving on to step 4:
When dividing 1607 by 438, we get 3 with a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1314 from 1607, we get 293.
Fetch the next digit (7) from the dividend, attach it to 293 and continue: 2937 / 438

Let's proceed to step 5:
If we divide 2937 by 438, we get 6 and a remainder of 309.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 2628 from 2937 to get 309.
Bring next digit (4) of the dividend behind the 309 and repeat the process: 3094 / 438

Going ahead to step 6:
438 goes into 3094 7 times with a remainder of 28.
The next digit of our result is 7. 
Result so far: 367.0
Subtracting 3066 from 3094 leaves us with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 438

Step 7:
438 can be fit into 284 0 times, resulting in a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 3670.0
Deduct 0 from 284 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 8:
If we divide 2840 by 438, we get 6 and a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 3670.6
Subtract 2628 from 2840 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
438 goes into 2120 4 times with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 3670.64
Subtracting 1752 from 2120 leaves us 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 10:
If we divide 3680 by 438, we get 8 and a remainder of 176.
The next digit of our result is 8. 
Result so far: 3670.648
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.

Advancing to step 11:
438 can be fit into 1760 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3670.6484
If we take 1752 away from 1760, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 438, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 3670.6484
Subtracting 0 from 80 leaves us with 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 13:
The number 438 fits into 800 1 times, leaving a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 3670.648401
Deduct 438 from 800 and we're left with 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 14:
If we divide 3620 by 438, we get 8 and a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 3670.6484018
If we take 3504 away from 3620, we end up 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.

On to step 15:
438 can be fit into 1160 2 times, resulting in a remainder of 284.
The number 2 becomes the next digit in our result. 
Result so far: 3670.64840182
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.

After the division, we end up with 3670.64840182 and a remainder of 2.84e-07.
