621741 divided by 49 
The aim is to understand the frequency of 49 in 621741.

Moving on to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 49

Moving on to step 2:
The number 49 fits into 62 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 49 from 62 leaves us with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 49

Let's proceed to step 3:
49 goes into 131 2 times with a remainder of 33.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 98 from 131 leaves us with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 49

Let's proceed to step 4:
When dividing 337 by 49, we get 6 with a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we subtract 294 from 337, we get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 49

Let's proceed to step 5:
49 can be fit into 434 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 1268.0
The remainder is 42 after subtracting 392 from 434.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 49

Moving on to step 6:
49 goes into 421 8 times with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 12688.0
If we subtract 392 from 421, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
49 can be fit into 290 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 12688.5
If we take 245 away from 290, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
450 divided by 49 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 12688.59
The remainder is 9 after subtracting 441 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
When dividing 90 by 49, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 12688.591
Subtract 49 from 90 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
49 goes into 410 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 12688.5918
Subtract 392 from 410 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
The number 49 fits into 180 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 12688.59183
Subtract 147 from 180 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
49 can be fit into 330 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 12688.591836
If we take 294 away from 330, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
49 can be fit into 360 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 12688.5918367
Subtract 343 from 360 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
49 goes into 170 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 12688.59183673
Subtracting 147 from 170 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 12688.59183673 with a remainder of 2.3e-08.
