20456678 ÷ 197 
The aim is to understand the frequency of 197 in 20456678.

Moving on to step 1:
197 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 197

Going ahead to step 2:
When dividing 20 by 197, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 197

On to step 3:
If we divide 204 by 197, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 197 from 204, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 197

Advancing to step 4:
When dividing 75 by 197, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 75, we get 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 197

Moving on to step 5:
197 can be fit into 756 3 times, resulting in a remainder of 165.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 591 from 756 and we're left with 165.
Include the next digit (6) from the dividend after 165, then repeat: 1656 / 197

Going ahead to step 6:
If we divide 1656 by 197, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 1038.0
Deduct 1576 from 1656 and we're left with 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 197

Advancing to step 7:
197 can be fit into 807 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 10384.0
Deduct 788 from 807 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 197

On to step 8:
The number 197 fits into 198 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 103841.0
Subtracting 197 from 198 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 197, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 103841.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
197 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 103841.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 103841.0, and the remainder is 0.1.
