We look at the division of 72032420 by 178 
The aim is to understand the frequency of 178 in 72032420.

Let's proceed to step 1:
The number 178 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 178

Let's proceed to step 2:
The number 178 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 178

Let's proceed to step 3:
When dividing 720 by 178, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 712 from 720 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 178

Advancing to step 4:
178 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 40.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 178

Moving on to step 5:
832 divided by 178 is 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 404.0
Subtract 712 from 832 to get 120.
Take the next digit (4) from the dividend and append it to 120, then repeat: 1204 / 178

On to step 6:
178 can be fit into 1204 6 times, resulting in a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 4046.0
Subtract 1068 from 1204 to get 136.
Append the next digit (2) from the dividend to 136 and continue with: 1362 / 178

Let's proceed to step 7:
178 can be fit into 1362 7 times, resulting in a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 40467.0
The remainder is 116 after subtracting 1246 from 1362.
Include the next digit (0) from the dividend after 116, then repeat: 1160 / 178

Advancing to step 8:
If we divide 1160 by 178, we get 6 and a remainder of 92.
The next digit of our result is 6. 
Result so far: 404676.0
If we subtract 1068 from 1160, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 9:
178 can be fit into 920 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 404676.5
Subtracting 890 from 920 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 178 fits into 300 1 times, leaving a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 404676.51
If we subtract 178 from 300, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 11:
178 can be fit into 1220 6 times, resulting in a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 404676.516
If we take 1068 away from 1220, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
1520 divided by 178 is 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 404676.5168
If we take 1424 away from 1520, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
178 goes into 960 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 404676.51685
The remainder is 70 after subtracting 890 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
If we divide 700 by 178, we get 3 and a remainder of 166.
Record the quotient 3 as the next digit in the result. 
Result so far: 404676.516853
If we subtract 534 from 700, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 15:
The number 178 fits into 1660 9 times, leaving a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 404676.5168539
If we take 1602 away from 1660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 16:
178 goes into 580 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 404676.51685393
Subtract 534 from 580 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 404676.51685393, and the remainder is 4.6e-08.
