We're dividing 51886378 by 203 
We want to divide 51886378 by 203.

On to step 1:
5 divided by 203 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 203

Moving on to step 2:
203 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 203

Let's proceed to step 3:
203 goes into 518 2 times with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 112 after subtracting 406 from 518.
Append the next digit (8) from the dividend to 112 and continue with: 1128 / 203

Let's proceed to step 4:
When dividing 1128 by 203, we get 5 with a remainder of 113.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 1015 from 1128 leaves us with 113.
Grab the next digit (6) from the dividend, add it to 113, then carry on: 1136 / 203

Advancing to step 5:
If we divide 1136 by 203, we get 5 and a remainder of 121.
Use 5 as the next digit of our solution. 
Result so far: 255.0
If we take 1015 away from 1136, we end up with 121.
Bring next digit (3) of the dividend behind the 121 and repeat the process: 1213 / 203

Step 6:
1213 divided by 203 is 5 with a remainder of 198.
The number 5 becomes the next digit in our result. 
Result so far: 2555.0
If we take 1015 away from 1213, we end up with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 203

Going ahead to step 7:
When dividing 1987 by 203, we get 9 with a remainder of 160.
Put 9 as the next digit of the answer. 
Result so far: 25559.0
If we subtract 1827 from 1987, we get 160.
Grab the next digit (8) from the dividend, add it to 160, then carry on: 1608 / 203

Step 8:
203 goes into 1608 7 times with a remainder of 187.
Write down 7 as next digit of the result. 
Result so far: 255597.0
The remainder is 187 after subtracting 1421 from 1608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 9:
1870 divided by 203 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 255597.9
If we subtract 1827 from 1870, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
When dividing 430 by 203, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 255597.92
Subtracting 406 from 430 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
203 goes into 240 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 255597.921
The remainder is 37 after subtracting 203 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 12:
203 can be fit into 370 1 times, resulting in a remainder of 167.
Record the quotient 1 as the next digit in the result. 
Result so far: 255597.9211
Subtracting 203 from 370 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

After the division, we end up with 255597.9211 and a remainder of 0.00167.
