We look at the division of 17691022 by 372 
The aim is to understand the frequency of 372 in 17691022.

Step 1:
372 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 372

Going ahead to step 2:
17 divided by 372 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 372

Step 3:
The number 372 fits into 176 0 times, leaving a remainder of 176.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 176, we get 176.
Bring next digit (9) of the dividend behind the 176 and repeat the process: 1769 / 372

Let's proceed to step 4:
372 goes into 1769 4 times with a remainder of 281.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1488 from 1769, we get 281.
Fetch the next digit (1) from the dividend, attach it to 281 and continue: 2811 / 372

Let's proceed to step 5:
The number 372 fits into 2811 7 times, leaving a remainder of 207.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 2604 away from 2811, we end up with 207.
Fetch the next digit (0) from the dividend, attach it to 207 and continue: 2070 / 372

Step 6:
2070 divided by 372 is 5 with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 475.0
Deduct 1860 from 2070 and we're left with 210.
Append the next digit (2) from the dividend to 210 and continue with: 2102 / 372

Step 7:
372 can be fit into 2102 5 times, resulting in a remainder of 242.
Record the quotient 5 as the next digit in the result. 
Result so far: 4755.0
If we subtract 1860 from 2102, we get 242.
Append the next digit (2) from the dividend to 242 and continue with: 2422 / 372

On to step 8:
When dividing 2422 by 372, we get 6 with a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 47556.0
Deduct 2232 from 2422 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
372 can be fit into 1900 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 47556.5
Subtracting 1860 from 1900 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
400 divided by 372 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 47556.51
If we take 372 away from 400, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
372 goes into 280 0 times with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 47556.51
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
If we divide 2800 by 372, we get 7 and a remainder of 196.
Use 7 as the next digit of our solution. 
Result so far: 47556.5107
The remainder is 196 after subtracting 2604 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 13:
372 can be fit into 1960 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 47556.51075
If we subtract 1860 from 1960, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
When dividing 1000 by 372, we get 2 with a remainder of 256.
The next digit of our result is 2. 
Result so far: 47556.510752
Subtract 744 from 1000 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
372 can be fit into 2560 6 times, resulting in a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 47556.5107526
Subtracting 2232 from 2560 leaves us 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.

Step 16:
372 goes into 3280 8 times with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 47556.51075268
The remainder is 304 after subtracting 2976 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 47556.51075268 with a remainder of 3.04e-07.
