15486020 ÷ 178 
The aim is to understand the frequency of 178 in 15486020.

Step 1:
1 divided by 178 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 178

Advancing to step 2:
178 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 178

On to step 3:
If we divide 154 by 178, we get 0 and a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 154 after subtracting 0 from 154.
Fetch the next digit (8) from the dividend, attach it to 154 and continue: 1548 / 178

On to step 4:
178 goes into 1548 8 times with a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 1424 from 1548 leaves us with 124.
Append the next digit (6) from the dividend to 124 and continue with: 1246 / 178

On to step 5:
If we divide 1246 by 178, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
The remainder is 0 after subtracting 1246 from 1246.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 178

On to step 6:
178 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 870.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 178

Going ahead to step 7:
178 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 8700.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 178

On to step 8:
If we divide 20 by 178, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 87000.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
178 goes into 200 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 87000.1
If we subtract 178 from 200, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
178 can be fit into 220 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 87000.11
The remainder is 42 after subtracting 178 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 87000.11 with a balance of 0.042.
