642902 ÷ 49 
We want to divide 642902 by 49.

Moving on to step 1:
The number 49 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 49

Advancing to step 2:
When dividing 64 by 49, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 49 from 64 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 49

Let's proceed to step 3:
When dividing 152 by 49, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 147 from 152, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 49

Let's proceed to step 4:
If we divide 59 by 49, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 131.0
The remainder is 10 after subtracting 49 from 59.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 49

Moving on to step 5:
The number 49 fits into 100 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1312.0
If we subtract 98 from 100, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 49

On to step 6:
If we divide 22 by 49, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 13120.0
Subtract 0 from 22 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.

Moving on to step 7:
The number 49 fits into 220 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 13120.4
If we subtract 196 from 220, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
49 can be fit into 240 4 times, resulting in a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 13120.44
If we subtract 196 from 240, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 13120.44, with a leftover of 0.044.
