51031438 ÷ 703 
Let's see how many times 703 fits into 51031438.

Moving on to step 1:
703 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 703

Let's proceed to step 2:
703 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 703

Advancing to step 3:
When dividing 510 by 703, we get 0 with a remainder of 510.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 510, we end up with 510.
Append the next digit (3) from the dividend to 510 and continue with: 5103 / 703

Step 4:
703 can be fit into 5103 7 times, resulting in a remainder of 182.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4921 from 5103 and we're left with 182.
Grab the next digit (1) from the dividend, add it to 182, then carry on: 1821 / 703

Advancing to step 5:
1821 divided by 703 is 2 with a remainder of 415.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 415 after subtracting 1406 from 1821.
Include the next digit (4) from the dividend after 415, then repeat: 4154 / 703

Step 6:
703 can be fit into 4154 5 times, resulting in a remainder of 639.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
If we take 3515 away from 4154, we end up with 639.
Include the next digit (3) from the dividend after 639, then repeat: 6393 / 703

Moving on to step 7:
703 goes into 6393 9 times with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 7259.0
The remainder is 66 after subtracting 6327 from 6393.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 703

On to step 8:
668 divided by 703 is 0 with a remainder of 668.
Record the quotient 0 as the next digit in the result. 
Result so far: 72590.0
Subtracting 0 from 668 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 9:
703 goes into 6680 9 times with a remainder of 353.
Write down 9 as next digit of the result. 
Result so far: 72590.9
If we subtract 6327 from 6680, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 10:
The number 703 fits into 3530 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 72590.95
Subtract 3515 from 3530 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
If we divide 150 by 703, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 72590.95
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
When dividing 1500 by 703, we get 2 with a remainder of 94.
The next digit of our result is 2. 
Result so far: 72590.9502
The remainder is 94 after subtracting 1406 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 13:
The number 703 fits into 940 1 times, leaving a remainder of 237.
Put 1 as the next digit of the answer. 
Result so far: 72590.95021
The remainder is 237 after subtracting 703 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 14:
The number 703 fits into 2370 3 times, leaving a remainder of 261.
The number 3 becomes the next digit in our result. 
Result so far: 72590.950213
If we take 2109 away from 2370, we end up with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 15:
The number 703 fits into 2610 3 times, leaving a remainder of 501.
The next digit of our result is 3. 
Result so far: 72590.9502133
Deduct 2109 from 2610 and we're left with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

After the division, we end up with 72590.9502133 and a remainder of 5.01e-06.
