Let's divide 51248318 by 203
We want to divide 51248318 by 203.

Step 1:
203 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 203

Moving on to step 2:
203 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 203

Going ahead to step 3:
If we divide 512 by 203, we get 2 and a remainder of 106.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 106 after subtracting 406 from 512.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 203

Step 4:
The number 203 fits into 1064 5 times, leaving a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 1015 from 1064 and we're left with 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 203

Moving on to step 5:
The number 203 fits into 498 2 times, leaving a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 252.0
Subtract 406 from 498 to get 92.
Include the next digit (3) from the dividend after 92, then repeat: 923 / 203

Step 6:
203 can be fit into 923 4 times, resulting in a remainder of 111.
Record the quotient 4 as the next digit in the result. 
Result so far: 2524.0
Subtracting 812 from 923 leaves us with 111.
Append the next digit (1) from the dividend to 111 and continue with: 1111 / 203

Advancing to step 7:
When dividing 1111 by 203, we get 5 with a remainder of 96.
Write down 5 as next digit of the result. 
Result so far: 25245.0
Subtracting 1015 from 1111 leaves us with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 203

Advancing to step 8:
203 can be fit into 968 4 times, resulting in a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 252454.0
If we take 812 away from 968, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 9:
1560 divided by 203 is 7 with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 252454.7
If we subtract 1421 from 1560, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 10:
The number 203 fits into 1390 6 times, leaving a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 252454.76
If we take 1218 away from 1390, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
1720 divided by 203 is 8 with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 252454.768
Subtract 1624 from 1720 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 12:
203 goes into 960 4 times with a remainder of 148.
The next digit of our result is 4. 
Result so far: 252454.7684
The remainder is 148 after subtracting 812 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 13:
203 can be fit into 1480 7 times, resulting in a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 252454.76847
Subtracting 1421 from 1480 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 14:
203 goes into 590 2 times with a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 252454.768472
If we subtract 406 from 590, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 15:
The number 203 fits into 1840 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 252454.7684729
The remainder is 13 after subtracting 1827 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 16:
130 divided by 203 is 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 252454.7684729
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 252454.7684729 with a remaining 1.3e-07.
