684190 divided by 49 
The aim is to understand the frequency of 49 in 684190.

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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 49

On to step 2:
If we divide 68 by 49, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 49 from 68 and we're left with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 49

On to step 3:
49 can be fit into 194 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 47 after subtracting 147 from 194.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 49

Let's proceed to step 4:
49 can be fit into 471 9 times, resulting in a remainder of 30.
The next digit of our result is 9. 
Result so far: 139.0
If we take 441 away from 471, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 49

On to step 5:
49 can be fit into 309 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 1396.0
Subtracting 294 from 309 leaves us with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 49

On to step 6:
49 goes into 150 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13963.0
Deduct 147 from 150 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
49 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 13963.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 49 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 13963.06
Subtracting 294 from 300 leaves us 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:
49 goes into 60 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 13963.061
If we subtract 49 from 60, we 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.

Step 10:
49 can be fit into 110 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 13963.0612
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.

On to step 11:
120 divided by 49 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 13963.06122
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 13963.06122 and a remainder of 2.2e-05.
