We look at the division of 642211 by 49 
The aim is to understand the frequency of 49 in 642211.

Moving on to step 1:
When dividing 6 by 49, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 49

On to step 2:
When dividing 64 by 49, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 49 away from 64, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 49

Going ahead to step 3:
The number 49 fits into 152 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 147 from 152, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 49

Moving on to step 4:
49 can be fit into 52 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we subtract 49 from 52, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 49

Going ahead to step 5:
The number 49 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 1310.0
Subtract 0 from 31 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 49

Going ahead to step 6:
When dividing 311 by 49, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 13106.0
Subtracting 294 from 311 leaves us 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.

Advancing to step 7:
170 divided by 49 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 13106.3
If we subtract 147 from 170, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
The number 49 fits into 230 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 13106.34
If we subtract 196 from 230, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 49 fits into 340 6 times, leaving a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 13106.346
If we take 294 away from 340, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
460 divided by 49 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 13106.3469
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 11:
49 goes into 190 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 13106.34693
If we subtract 147 from 190, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
When dividing 430 by 49, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 13106.346938
The remainder is 38 after subtracting 392 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
49 goes into 380 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13106.3469387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
The number 49 fits into 370 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 13106.34693877
If we subtract 343 from 370, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 13106.34693877 with a remainder of 2.7e-08.
