We divide 687990 by 49
We're looking to find how many times 49 goes into 687990.

Moving on to step 1:
6 divided by 49 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 49

Let's proceed to step 2:
If we divide 68 by 49, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 49 from 68 and we're left with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 49

Moving on to step 3:
When dividing 197 by 49, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 1 after subtracting 196 from 197.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 49

Advancing to step 4:
If we divide 19 by 49, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
If we subtract 0 from 19, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 49

On to step 5:
When dividing 199 by 49, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1404.0
If we subtract 196 from 199, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 49

Let's proceed to step 6:
49 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 14040.0
Deduct 0 from 30 and we're left 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.

Advancing to step 7:
49 goes into 300 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 14040.6
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
49 can be fit into 60 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 14040.61
The remainder is 11 after subtracting 49 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
49 goes into 110 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 14040.612
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.

Moving on to step 10:
If we divide 120 by 49, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 14040.6122
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.

Our division results in 14040.6122 with a remaining 0.00022.
