We look at the division of 20157710 by 949 
We want to divide 20157710 by 949.

Step 1:
The number 949 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 949

Let's proceed to step 2:
20 divided by 949 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 949

Advancing to step 3:
The number 949 fits into 201 0 times, leaving a remainder of 201.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 201 leaves us with 201.
Grab the next digit (5) from the dividend, add it to 201, then carry on: 2015 / 949

Advancing to step 4:
If we divide 2015 by 949, we get 2 and a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1898 away from 2015, we end up with 117.
Grab the next digit (7) from the dividend, add it to 117, then carry on: 1177 / 949

Step 5:
949 goes into 1177 1 times with a remainder of 228.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 949 from 1177, we get 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 949

On to step 6:
The number 949 fits into 2287 2 times, leaving a remainder of 389.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
If we subtract 1898 from 2287, we get 389.
Bring next digit (1) of the dividend behind the 389 and repeat the process: 3891 / 949

On to step 7:
If we divide 3891 by 949, we get 4 and a remainder of 95.
The next digit of our result is 4. 
Result so far: 2124.0
If we take 3796 away from 3891, we end up with 95.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 949

Step 8:
If we divide 950 by 949, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 21241.0
Deduct 949 from 950 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
949 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 21241.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 949, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 21241.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 21241.0 with a remaining 0.1.
