51840646 divided by 103 
Our goal is to divide 51840646 by 103.

Step 1:
103 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 103

Subtract 0 from 51 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 103

On to step 3:
The number 103 fits into 518 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 515 from 518 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 103

Moving on to step 4:
103 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 103

Let's proceed to step 5:
103 goes into 340 3 times with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 503.0
If we subtract 309 from 340, we get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 103

Step 6:
The number 103 fits into 316 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 5033.0
If we subtract 309 from 316, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 103

Let's proceed to step 7:
103 can be fit into 74 0 times, resulting in a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 50330.0
Subtract 0 from 74 to get 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 103

Advancing to step 8:
746 divided by 103 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 503307.0
If we subtract 721 from 746, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 103 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 503307.2
Subtracting 206 from 250 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 103, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 503307.24
Deduct 412 from 440 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
103 goes into 280 2 times with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 503307.242
Deduct 206 from 280 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 12:
103 can be fit into 740 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 503307.2427
If we take 721 away from 740, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
The number 103 fits into 190 1 times, leaving a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 503307.24271
If we subtract 103 from 190, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 14:
When dividing 870 by 103, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 503307.242718
Subtract 824 from 870 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
103 can be fit into 460 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 503307.2427184
If we take 412 away from 460, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
103 goes into 480 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 503307.24271844
Subtracting 412 from 480 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 503307.24271844 with a remainder of 6.8e-08.
