We divide 641344 by 49
The aim is to understand the frequency of 49 in 641344.

Let's proceed to step 1:
The number 49 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 49

On to step 2:
49 can be fit into 64 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 49 from 64 and we're left with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 49

Going ahead to step 3:
If we divide 151 by 49, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 147 from 151 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 49

Going ahead to step 4:
49 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 43, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 49

Step 5:
49 goes into 434 8 times with a remainder of 42.
The next digit of our result is 8. 
Result so far: 1308.0
The remainder is 42 after subtracting 392 from 434.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 49

Let's proceed to step 6:
The number 49 fits into 424 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 13088.0
If we take 392 away from 424, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
The number 49 fits into 320 6 times, leaving a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 13088.6
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
When dividing 260 by 49, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13088.65
Subtract 245 from 260 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
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: 13088.653
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
If we divide 30 by 49, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13088.653
If we subtract 0 from 30, we 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.

On to step 11:
300 divided by 49 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 13088.65306
Deduct 294 from 300 and we're left 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 12:
49 goes into 60 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 13088.653061
Subtract 49 from 60 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
When dividing 110 by 49, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 13088.6530612
If we take 98 away from 110, we end up 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.

Advancing to step 14:
49 goes into 120 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 13088.65306122
Deduct 98 from 120 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 13088.65306122, with a leftover of 2.2e-08.
