Let's divide 74289029 by 28
The aim is to understand the frequency of 28 in 74289029.

Let's proceed to step 1:
7 divided by 28 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 28

Advancing to step 2:
If we divide 74 by 28, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 56 away from 74, we end up with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 28

Advancing to step 3:
The number 28 fits into 182 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 168 from 182 and we're left with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 28

Advancing to step 4:
28 goes into 148 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Deduct 140 from 148 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 28

Step 5:
If we divide 89 by 28, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 2653.0
If we subtract 84 from 89, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 28

Advancing to step 6:
The number 28 fits into 50 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 26531.0
The remainder is 22 after subtracting 28 from 50.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 28

Let's proceed to step 7:
If we divide 222 by 28, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 265317.0
The remainder is 26 after subtracting 196 from 222.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 28

Let's proceed to step 8:
The number 28 fits into 269 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 2653179.0
Deduct 252 from 269 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 28 fits into 170 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 2653179.6
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
If we divide 20 by 28, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2653179.6
If we take 0 away from 20, we end up 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.

Moving on to step 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 2653179.607
If we take 196 away from 200, we end up 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.

Step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2653179.6071
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2653179.60714
If we take 112 away from 120, 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.

Going ahead to step 14:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2653179.607142
Deduct 56 from 80 and we're left with 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 15:
240 divided by 28 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2653179.6071428
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 16:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2653179.60714285
If we take 140 away from 160, we end up 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.

The final outcome is 2653179.60714285, with a leftover of 2e-08.
