We look at the division of 78404805 by 372 
The aim is to understand the frequency of 372 in 78404805.

Moving on to step 1:
372 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 372

On to step 2:
When dividing 78 by 372, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 372

Advancing to step 3:
If we divide 784 by 372, we get 2 and a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 744 from 784 to get 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 372

Moving on to step 4:
400 divided by 372 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 28 after subtracting 372 from 400.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 372

Step 5:
372 goes into 284 0 times with a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 210.0
Deduct 0 from 284 and we're left with 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 372

Advancing to step 6:
If we divide 2848 by 372, we get 7 and a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 2107.0
If we subtract 2604 from 2848, we get 244.
Grab the next digit (0) from the dividend, add it to 244, then carry on: 2440 / 372

Let's proceed to step 7:
When dividing 2440 by 372, we get 6 with a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 21076.0
Subtract 2232 from 2440 to get 208.
Fetch the next digit (5) from the dividend, attach it to 208 and continue: 2085 / 372

Advancing to step 8:
2085 divided by 372 is 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 210765.0
Deduct 1860 from 2085 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
2250 divided by 372 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 210765.6
Subtracting 2232 from 2250 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 372 fits into 180 0 times, leaving a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 210765.6
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
1800 divided by 372 is 4 with a remainder of 312.
Write down 4 as next digit of the result. 
Result so far: 210765.604
Subtract 1488 from 1800 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 12:
372 can be fit into 3120 8 times, resulting in a remainder of 144.
The next digit of our result is 8. 
Result so far: 210765.6048
Deduct 2976 from 3120 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
372 can be fit into 1440 3 times, resulting in a remainder of 324.
The next digit of our result is 3. 
Result so far: 210765.60483
If we subtract 1116 from 1440, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 14:
372 can be fit into 3240 8 times, resulting in a remainder of 264.
Record the quotient 8 as the next digit in the result. 
Result so far: 210765.604838
If we subtract 2976 from 3240, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 15:
372 goes into 2640 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 210765.6048387
The remainder is 36 after subtracting 2604 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
360 divided by 372 is 0 with a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 210765.6048387
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 210765.6048387 with a remainder of 3.6e-07.
