643318 ÷ 49 
The aim is to understand the frequency of 49 in 643318.

Step 1:
The number 49 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 49

Step 2:
64 divided by 49 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 15 after subtracting 49 from 64.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 49

On to step 3:
If we divide 153 by 49, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 147 away from 153, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 49

On to step 4:
49 can be fit into 63 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Subtracting 49 from 63 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 49

Moving on to step 5:
49 can be fit into 141 2 times, resulting in a remainder of 43.
The next digit of our result is 2. 
Result so far: 1312.0
Subtracting 98 from 141 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 49

Going ahead to step 6:
When dividing 438 by 49, we get 8 with a remainder of 46.
The next digit of our result is 8. 
Result so far: 13128.0
Subtract 392 from 438 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
49 goes into 460 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 13128.9
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
190 divided by 49 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 13128.93
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.

Step 9:
49 goes into 430 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 13128.938
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.

Step 10:
If we divide 380 by 49, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 13128.9387
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.

Advancing to step 11:
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: 13128.93877
If we take 343 away from 370, we end up with 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 quotient of the division is 13128.93877, and the remainder is 2.7e-05.
