We're dividing 45421339 by 379 
The aim is to understand the frequency of 379 in 45421339.

Step 1:
The number 379 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 379

Advancing to step 2:
The number 379 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 379

Moving on to step 3:
If we divide 454 by 379, we get 1 and a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 379 from 454 to get 75.
Include the next digit (2) from the dividend after 75, then repeat: 752 / 379

Moving on to step 4:
379 goes into 752 1 times with a remainder of 373.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 373 after subtracting 379 from 752.
Bring next digit (1) of the dividend behind the 373 and repeat the process: 3731 / 379

Let's proceed to step 5:
379 can be fit into 3731 9 times, resulting in a remainder of 320.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 3411 from 3731 leaves us with 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 379

Step 6:
If we divide 3203 by 379, we get 8 and a remainder of 171.
The number 8 becomes the next digit in our result. 
Result so far: 1198.0
If we subtract 3032 from 3203, we get 171.
Bring next digit (3) of the dividend behind the 171 and repeat the process: 1713 / 379

Going ahead to step 7:
When dividing 1713 by 379, we get 4 with a remainder of 197.
Record the quotient 4 as the next digit in the result. 
Result so far: 11984.0
The remainder is 197 after subtracting 1516 from 1713.
Bring next digit (9) of the dividend behind the 197 and repeat the process: 1979 / 379

Let's proceed to step 8:
The number 379 fits into 1979 5 times, leaving a remainder of 84.
Write down 5 as next digit of the result. 
Result so far: 119845.0
Deduct 1895 from 1979 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 9:
379 can be fit into 840 2 times, resulting in a remainder of 82.
The next digit of our result is 2. 
Result so far: 119845.2
If we take 758 away from 840, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
820 divided by 379 is 2 with a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 119845.22
If we subtract 758 from 820, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 119845.22 with a remaining 0.062.
