We're dividing 5684698 by 438 
The aim is to understand the frequency of 438 in 5684698.

Advancing to step 1:
If we divide 5 by 438, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 438

On to step 2:
56 divided by 438 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (8) from the dividend and append it to 56, then repeat: 568 / 438

Going ahead to step 3:
438 goes into 568 1 times with a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 438 from 568 to get 130.
Bring next digit (4) of the dividend behind the 130 and repeat the process: 1304 / 438

Moving on to step 4:
When dividing 1304 by 438, we get 2 with a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 876 away from 1304, we end up with 428.
Take the next digit (6) from the dividend and append it to 428, then repeat: 4286 / 438

On to step 5:
438 goes into 4286 9 times with a remainder of 344.
Use 9 as the next digit of our solution. 
Result so far: 129.0
The remainder is 344 after subtracting 3942 from 4286.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 438

Let's proceed to step 6:
438 can be fit into 3449 7 times, resulting in a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
If we take 3066 away from 3449, we end up with 383.
Grab the next digit (8) from the dividend, add it to 383, then carry on: 3838 / 438

On to step 7:
When dividing 3838 by 438, we get 8 with a remainder of 334.
The next digit of our result is 8. 
Result so far: 12978.0
If we take 3504 away from 3838, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 8:
When dividing 3340 by 438, we get 7 with a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 12978.7
Subtracting 3066 from 3340 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 9:
2740 divided by 438 is 6 with a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 12978.76
If we take 2628 away from 2740, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 10:
438 can be fit into 1120 2 times, resulting in a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 12978.762
If we take 876 away from 1120, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 11:
If we divide 2440 by 438, we get 5 and a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 12978.7625
If we subtract 2190 from 2440, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
When dividing 2500 by 438, we get 5 with a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 12978.76255
Deduct 2190 from 2500 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 12978.76255 and a remainder of 0.00031.
