1486406 divided by 372 
The aim is to understand the frequency of 372 in 1486406.

Let's proceed to step 1:
If we divide 1 by 372, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 372

Moving on to step 2:
14 divided by 372 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 372

Advancing to step 3:
When dividing 148 by 372, we get 0 with a remainder of 148.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 148 leaves us with 148.
Bring next digit (6) of the dividend behind the 148 and repeat the process: 1486 / 372

On to step 4:
1486 divided by 372 is 3 with a remainder of 370.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 370 after subtracting 1116 from 1486.
Append the next digit (4) from the dividend to 370 and continue with: 3704 / 372

Step 5:
The number 372 fits into 3704 9 times, leaving a remainder of 356.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 3348 from 3704 to get 356.
Bring next digit (0) of the dividend behind the 356 and repeat the process: 3560 / 372

Step 6:
372 can be fit into 3560 9 times, resulting in a remainder of 212.
The next digit of our result is 9. 
Result so far: 399.0
Subtract 3348 from 3560 to get 212.
Append the next digit (6) from the dividend to 212 and continue with: 2126 / 372

Step 7:
The number 372 fits into 2126 5 times, leaving a remainder of 266.
The next digit of our result is 5. 
Result so far: 3995.0
If we subtract 1860 from 2126, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 8:
When dividing 2660 by 372, we get 7 with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 3995.7
If we take 2604 away from 2660, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
372 goes into 560 1 times with a remainder of 188.
Write down 1 as next digit of the result. 
Result so far: 3995.71
Subtracting 372 from 560 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 10:
When dividing 1880 by 372, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 3995.715
Subtract 1860 from 1880 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 372 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 3995.715
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
When dividing 2000 by 372, we get 5 with a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 3995.71505
Subtracting 1860 from 2000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
372 can be fit into 1400 3 times, resulting in a remainder of 284.
Record the quotient 3 as the next digit in the result. 
Result so far: 3995.715053
If we take 1116 away from 1400, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 14:
372 goes into 2840 7 times with a remainder of 236.
Put 7 as the next digit of the answer. 
Result so far: 3995.7150537
Subtracting 2604 from 2840 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 15:
372 can be fit into 2360 6 times, resulting in a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 3995.71505376
If we take 2232 away from 2360, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 3995.71505376, with a leftover of 1.28e-07.
