We divide 79185217 by 438
The aim is to understand the frequency of 438 in 79185217.

Advancing to step 1:
If we divide 7 by 438, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 438

Let's proceed to step 2:
If we divide 79 by 438, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 438

On to step 3:
When dividing 791 by 438, we get 1 with a remainder of 353.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 438 from 791 leaves us with 353.
Take the next digit (8) from the dividend and append it to 353, then repeat: 3538 / 438

Step 4:
When dividing 3538 by 438, we get 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 3504 away from 3538, we end up with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 438

On to step 5:
345 divided by 438 is 0 with a remainder of 345.
Use 0 as the next digit of our solution. 
Result so far: 180.0
The remainder is 345 after subtracting 0 from 345.
Include the next digit (2) from the dividend after 345, then repeat: 3452 / 438

Let's proceed to step 6:
438 can be fit into 3452 7 times, resulting in a remainder of 386.
Use 7 as the next digit of our solution. 
Result so far: 1807.0
Subtract 3066 from 3452 to get 386.
Include the next digit (1) from the dividend after 386, then repeat: 3861 / 438

Let's proceed to step 7:
438 goes into 3861 8 times with a remainder of 357.
The number 8 becomes the next digit in our result. 
Result so far: 18078.0
If we subtract 3504 from 3861, we get 357.
Grab the next digit (7) from the dividend, add it to 357, then carry on: 3577 / 438

On to step 8:
When dividing 3577 by 438, we get 8 with a remainder of 73.
The next digit of our result is 8. 
Result so far: 180788.0
Deduct 3504 from 3577 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 9:
438 can be fit into 730 1 times, resulting in a remainder of 292.
Use 1 as the next digit of our solution. 
Result so far: 180788.1
Subtract 438 from 730 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 10:
438 can be fit into 2920 6 times, resulting in a remainder of 292.
The next digit of our result is 6. 
Result so far: 180788.16
If we take 2628 away from 2920, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
If we divide 2920 by 438, we get 6 and a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 180788.166
The remainder is 292 after subtracting 2628 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 180788.166 and a remainder of 0.0292.
