We look at the division of 553581 by 49 
The aim is to understand the frequency of 49 in 553581.

Moving on to step 1:
When dividing 5 by 49, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 49

Advancing to step 2:
When dividing 55 by 49, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 49 from 55 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 49

Advancing to step 3:
49 can be fit into 63 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 14 after subtracting 49 from 63.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 49

On to step 4:
If we divide 145 by 49, we get 2 and a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
If we take 98 away from 145, we end up with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 49

Going ahead to step 5:
478 divided by 49 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1129.0
Deduct 441 from 478 and we're left with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 49

Advancing to step 6:
49 can be fit into 371 7 times, resulting in a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 11297.0
The remainder is 28 after subtracting 343 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
49 goes into 280 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 11297.5
If we subtract 245 from 280, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
350 divided by 49 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 11297.57
If we take 343 away from 350, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
49 can be fit into 70 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 11297.571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11297.5714
Subtracting 196 from 210 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.

Advancing to step 11:
49 can be fit into 140 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 11297.57142
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
If we divide 420 by 49, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 11297.571428
If we subtract 392 from 420, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 49, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 11297.5714285
Deduct 245 from 280 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
49 can be fit into 350 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 11297.57142857
Deduct 343 from 350 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 11297.57142857 and a remainder of 7e-09.
