We're dividing 666946 by 49 
The aim is to understand the frequency of 49 in 666946.

Let's proceed to step 1:
If we divide 6 by 49, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 49

Step 2:
49 goes into 66 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 49 from 66, we get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 49

Let's proceed to step 3:
176 divided by 49 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 147 away from 176, we end up with 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 49

Moving on to step 4:
If we divide 299 by 49, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 136.0
The remainder is 5 after subtracting 294 from 299.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 49

Advancing to step 5:
49 goes into 54 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1361.0
Deduct 49 from 54 and we're left with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 49

Advancing to step 6:
When dividing 56 by 49, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 13611.0
If we take 49 away from 56, 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.

Advancing to step 7:
49 can be fit into 70 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 13611.1
Deduct 49 from 70 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 13611.14
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.

Step 9:
When dividing 140 by 49, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 13611.142
If we subtract 98 from 140, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
49 goes into 420 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 13611.1428
Subtracting 392 from 420 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 49, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 13611.14285
The remainder is 35 after subtracting 245 from 280.
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 12:
When dividing 350 by 49, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 13611.142857
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.

On to step 13:
49 can be fit into 70 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 13611.1428571
Deduct 49 from 70 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
When dividing 210 by 49, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 13611.14285714
Deduct 196 from 210 and we're left 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.

After the division, we end up with 13611.14285714 and a remainder of 1.4e-08.
