We're dividing 51453838 by 102 
Our goal is to divide 51453838 by 102.

Step 1:
When dividing 5 by 102, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 102

Moving on to step 2:
102 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 102

Step 3:
When dividing 514 by 102, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 510 from 514 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 102

Moving on to step 4:
If we divide 45 by 102, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 45 to get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 102

Advancing to step 5:
453 divided by 102 is 4 with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 504.0
If we subtract 408 from 453, we get 45.
Bring next digit (8) of the dividend behind the 45 and repeat the process: 458 / 102

Let's proceed to step 6:
458 divided by 102 is 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 5044.0
If we take 408 away from 458, we end up with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 102

Advancing to step 7:
When dividing 503 by 102, we get 4 with a remainder of 95.
The number 4 becomes the next digit in our result. 
Result so far: 50444.0
Subtract 408 from 503 to get 95.
Grab the next digit (8) from the dividend, add it to 95, then carry on: 958 / 102

Advancing to step 8:
958 divided by 102 is 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 504449.0
If we take 918 away from 958, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 102, we get 3 with a remainder of 94.
The next digit of our result is 3. 
Result so far: 504449.3
Deduct 306 from 400 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 10:
940 divided by 102 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 504449.39
If we subtract 918 from 940, we 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.

Let's proceed to step 11:
If we divide 220 by 102, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 504449.392
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 102 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 504449.3921
The remainder is 58 after subtracting 102 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
102 can be fit into 580 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 504449.39215
Subtract 510 from 580 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
If we divide 700 by 102, we get 6 and a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 504449.392156
Subtracting 612 from 700 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 15:
When dividing 880 by 102, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 504449.3921568
Subtract 816 from 880 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
If we divide 640 by 102, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 504449.39215686
Subtract 612 from 640 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 504449.39215686 with a remainder of 2.8e-08.
