We divide 3390394 by 125
The aim is to understand the frequency of 125 in 3390394.

Advancing to step 1:
3 divided by 125 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 125

Step 2:
When dividing 33 by 125, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 125

Going ahead to step 3:
125 goes into 339 2 times with a remainder of 89.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 250 from 339 and we're left with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 125

On to step 4:
890 divided by 125 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 875 from 890, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 125

Advancing to step 5:
153 divided by 125 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Deduct 125 from 153 and we're left with 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 125

Going ahead to step 6:
289 divided by 125 is 2 with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 2712.0
Subtract 250 from 289 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 125

Step 7:
394 divided by 125 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 27123.0
If we take 375 away from 394, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
When dividing 190 by 125, we get 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 27123.1
Subtract 125 from 190 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
When dividing 650 by 125, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 27123.15
Subtracting 625 from 650 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
If we divide 250 by 125, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 27123.152
Subtract 250 from 250 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 125, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 27123.152
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 125, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27123.152
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 27123.152, and the remainder is 0.0.
