78879073 divided by 372 
The aim is to understand the frequency of 372 in 78879073.

Advancing to step 1:
7 divided by 372 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 372

Step 2:
372 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 372

Let's proceed to step 3:
When dividing 788 by 372, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 744 from 788 leaves us with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 372

Advancing to step 4:
372 can be fit into 447 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 372 from 447 leaves us with 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 372

Step 5:
When dividing 759 by 372, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
If we take 744 away from 759, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 372

Advancing to step 6:
372 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 2120.0
Subtracting 0 from 150 leaves us with 150.
Take the next digit (7) from the dividend and append it to 150, then repeat: 1507 / 372

Step 7:
When dividing 1507 by 372, we get 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 21204.0
If we subtract 1488 from 1507, we get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 372

Step 8:
372 goes into 193 0 times with a remainder of 193.
Use 0 as the next digit of our solution. 
Result so far: 212040.0
Deduct 0 from 193 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 9:
The number 372 fits into 1930 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 212040.5
Subtract 1860 from 1930 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
372 can be fit into 700 1 times, resulting in a remainder of 328.
Record the quotient 1 as the next digit in the result. 
Result so far: 212040.51
Deduct 372 from 700 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 11:
372 can be fit into 3280 8 times, resulting in a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 212040.518
Deduct 2976 from 3280 and we're left with 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 12:
If we divide 3040 by 372, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 212040.5188
Deduct 2976 from 3040 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 212040.5188 with a remainder of 0.00064.
