We're dividing 390918 by 29 
The aim is to understand the frequency of 29 in 390918.

Going ahead to step 1:
29 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 29

On to step 2:
39 divided by 29 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 29 away from 39, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 29

Step 3:
When dividing 100 by 29, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 87 from 100 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 29

Step 4:
The number 29 fits into 139 4 times, leaving a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 134.0
If we take 116 away from 139, we end up with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 29

Advancing to step 5:
The number 29 fits into 231 7 times, leaving a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 1347.0
The remainder is 28 after subtracting 203 from 231.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 29

Let's proceed to step 6:
29 goes into 288 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 13479.0
The remainder is 27 after subtracting 261 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
If we divide 270 by 29, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 13479.9
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
29 can be fit into 90 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13479.93
The remainder is 3 after subtracting 87 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 29, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 13479.931
Subtract 29 from 30 to 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.

Advancing to step 10:
The number 29 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 13479.931
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 29, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 13479.93103
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 29 fits into 130 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 13479.931034
Subtracting 116 from 130 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 29, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 13479.9310344
If we take 116 away from 140, we end up 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.

The quotient of the division is 13479.9310344, and the remainder is 2.4e-07.
