We look at the division of 69938 by 49 
The aim is to understand the frequency of 49 in 69938.

On to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 49

Step 2:
69 divided by 49 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 49 from 69 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 49

Moving on to step 3:
When dividing 209 by 49, we get 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 196 from 209 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 49

Let's proceed to step 4:
The number 49 fits into 133 2 times, leaving a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 142.0
The remainder is 35 after subtracting 98 from 133.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 49

Going ahead to step 5:
The number 49 fits into 358 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1427.0
Deduct 343 from 358 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
If we divide 150 by 49, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1427.3
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 49 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1427.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
49 can be fit into 300 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 1427.306
If we take 294 away from 300, 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.

Moving on to step 9:
If we divide 60 by 49, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1427.3061
If we take 49 away from 60, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 49 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1427.30612
Deduct 98 from 110 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.

Going ahead to step 11:
49 can be fit into 120 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1427.306122
Subtract 98 from 120 to 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.

After the division, we end up with 1427.306122 and a remainder of 2.2e-06.
