We're dividing 3793379 by 678 
The aim is to understand the frequency of 678 in 3793379.

On to step 1:
678 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 678

Let's proceed to step 2:
The number 678 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 678

Let's proceed to step 3:
678 goes into 379 0 times with a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Grab the next digit (3) from the dividend, add it to 379, then carry on: 3793 / 678

Let's proceed to step 4:
678 can be fit into 3793 5 times, resulting in a remainder of 403.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3390 away from 3793, we end up with 403.
Take the next digit (3) from the dividend and append it to 403, then repeat: 4033 / 678

Let's proceed to step 5:
The number 678 fits into 4033 5 times, leaving a remainder of 643.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtract 3390 from 4033 to get 643.
Bring next digit (7) of the dividend behind the 643 and repeat the process: 6437 / 678

Going ahead to step 6:
When dividing 6437 by 678, we get 9 with a remainder of 335.
Put 9 as the next digit of the answer. 
Result so far: 559.0
Subtract 6102 from 6437 to get 335.
Bring next digit (9) of the dividend behind the 335 and repeat the process: 3359 / 678

Step 7:
When dividing 3359 by 678, we get 4 with a remainder of 647.
The number 4 becomes the next digit in our result. 
Result so far: 5594.0
Subtract 2712 from 3359 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 8:
When dividing 6470 by 678, we get 9 with a remainder of 368.
Use 9 as the next digit of our solution. 
Result so far: 5594.9
Subtract 6102 from 6470 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 9:
678 goes into 3680 5 times with a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 5594.95
Deduct 3390 from 3680 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
678 goes into 2900 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 5594.954
If we subtract 2712 from 2900, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 11:
If we divide 1880 by 678, we get 2 and a remainder of 524.
The number 2 becomes the next digit in our result. 
Result so far: 5594.9542
Subtract 1356 from 1880 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 12:
When dividing 5240 by 678, we get 7 with a remainder of 494.
The next digit of our result is 7. 
Result so far: 5594.95427
The remainder is 494 after subtracting 4746 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Let's proceed to step 13:
678 can be fit into 4940 7 times, resulting in a remainder of 194.
Record the quotient 7 as the next digit in the result. 
Result so far: 5594.954277
Subtracting 4746 from 4940 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

After the division, we end up with 5594.954277 and a remainder of 1.94e-05.
