178944 ÷ 7 
The aim is to understand the frequency of 7 in 178944.

On to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 7

Step 2:
When dividing 17 by 7, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 14 from 17 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 7

Going ahead to step 3:
7 goes into 38 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 3 after subtracting 35 from 38.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 7

Let's proceed to step 4:
If we divide 39 by 7, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 255.0
Deduct 35 from 39 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Moving on to step 5:
7 can be fit into 44 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2556.0
If we subtract 42 from 44, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 7

Step 6:
7 can be fit into 24 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 25563.0
Subtract 21 from 24 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 25563.4
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 25563.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 25563.428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25563.4285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 25563.42857
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 25563.428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 25563.4285714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 25563.42857142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 25563.42857142, and the remainder is 6e-09.
