We're dividing 378991 by 56 
The aim is to understand the frequency of 56 in 378991.

Advancing to step 1:
If we divide 3 by 56, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 56

Let's proceed to step 2:
When dividing 37 by 56, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 56

Step 3:
56 goes into 378 6 times with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 336 from 378, we get 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 56

Moving on to step 4:
56 goes into 429 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 392 from 429 leaves us with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 56

Advancing to step 5:
When dividing 379 by 56, we get 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
If we take 336 away from 379, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 56

Moving on to step 6:
If we divide 431 by 56, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 6767.0
Subtracting 392 from 431 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
56 can be fit into 390 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6767.6
Subtract 336 from 390 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
56 goes into 540 9 times with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 6767.69
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
If we divide 360 by 56, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6767.696
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
When dividing 240 by 56, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 6767.6964
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
When dividing 160 by 56, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 6767.69642
Subtract 112 from 160 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
56 goes into 480 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6767.696428
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
The number 56 fits into 320 5 times, leaving a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 6767.6964285
If we subtract 280 from 320, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
56 goes into 400 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 6767.69642857
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 6767.69642857 with a remaining 8e-09.
