We're dividing 3959348 by 954 
The aim is to understand the frequency of 954 in 3959348.

On to step 1:
3 divided by 954 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 954

Step 2:
954 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 954

Step 3:
954 can be fit into 395 0 times, resulting in a remainder of 395.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 395, we end up with 395.
Grab the next digit (9) from the dividend, add it to 395, then carry on: 3959 / 954

On to step 4:
954 goes into 3959 4 times with a remainder of 143.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3816 away from 3959, we end up with 143.
Grab the next digit (3) from the dividend, add it to 143, then carry on: 1433 / 954

Advancing to step 5:
954 goes into 1433 1 times with a remainder of 479.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 954 from 1433 and we're left with 479.
Take the next digit (4) from the dividend and append it to 479, then repeat: 4794 / 954

Advancing to step 6:
The number 954 fits into 4794 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 415.0
If we take 4770 away from 4794, we end up with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 954

Let's proceed to step 7:
The number 954 fits into 248 0 times, leaving a remainder of 248.
The next digit of our result is 0. 
Result so far: 4150.0
The remainder is 248 after subtracting 0 from 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 8:
2480 divided by 954 is 2 with a remainder of 572.
Record the quotient 2 as the next digit in the result. 
Result so far: 4150.2
If we subtract 1908 from 2480, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Let's proceed to step 9:
5720 divided by 954 is 5 with a remainder of 950.
Put 5 as the next digit of the answer. 
Result so far: 4150.25
Subtracting 4770 from 5720 leaves us with 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Advancing to step 10:
9500 divided by 954 is 9 with a remainder of 914.
Use 9 as the next digit of our solution. 
Result so far: 4150.259
The remainder is 914 after subtracting 8586 from 9500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

Going ahead to step 11:
954 can be fit into 9140 9 times, resulting in a remainder of 554.
Use 9 as the next digit of our solution. 
Result so far: 4150.2599
Deduct 8586 from 9140 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

After the division, we end up with 4150.2599 and a remainder of 0.00554.
