366639 ÷ 49 
Our goal is to divide 366639 by 49.

On to step 1:
49 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 49

On to step 2:
When dividing 36 by 49, we get 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 49

Step 3:
The number 49 fits into 366 7 times, leaving a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 343 from 366, we get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 49

Let's proceed to step 4:
When dividing 236 by 49, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 40 after subtracting 196 from 236.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 49

Advancing to step 5:
403 divided by 49 is 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 748.0
If we subtract 392 from 403, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 49

Going ahead to step 6:
49 goes into 119 2 times with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 7482.0
If we take 98 away from 119, we end up 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.

Moving on to step 7:
When dividing 210 by 49, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 7482.4
If we take 196 away from 210, we end up 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.

Moving on to step 8:
49 goes into 140 2 times with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 7482.42
Subtract 98 from 140 to 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.

Moving on to step 9:
When dividing 420 by 49, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 7482.428
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
49 can be fit into 280 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7482.4285
Subtract 245 from 280 to get 35.
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 11:
If we divide 350 by 49, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7482.42857
The remainder is 7 after subtracting 343 from 350.
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 12:
70 divided by 49 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 7482.428571
Subtract 49 from 70 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
49 can be fit into 210 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 7482.4285714
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.

Advancing to step 14:
When dividing 140 by 49, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 7482.42857142
The remainder is 42 after subtracting 98 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 7482.42857142 and a remainder of 4.2e-08.
