We look at the division of 51303918 by 349 
Let's see how many times 349 fits into 51303918.

Step 1:
When dividing 5 by 349, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 349

Step 2:
51 divided by 349 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 349

Advancing to step 3:
513 divided by 349 is 1 with a remainder of 164.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 349 from 513 to get 164.
Grab the next digit (0) from the dividend, add it to 164, then carry on: 1640 / 349

Advancing to step 4:
349 can be fit into 1640 4 times, resulting in a remainder of 244.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1396 from 1640 and we're left with 244.
Take the next digit (3) from the dividend and append it to 244, then repeat: 2443 / 349

Step 5:
349 can be fit into 2443 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Subtract 2443 from 2443 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 349

Advancing to step 6:
349 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 1470.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 349

Advancing to step 7:
91 divided by 349 is 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 14700.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 349

On to step 8:
When dividing 918 by 349, we get 2 with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 147002.0
The remainder is 220 after subtracting 698 from 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 9:
349 goes into 2200 6 times with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 147002.6
Subtracting 2094 from 2200 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
When dividing 1060 by 349, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 147002.63
The remainder is 13 after subtracting 1047 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
349 goes into 130 0 times with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 147002.63
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 12:
When dividing 1300 by 349, we get 3 with a remainder of 253.
The next digit of our result is 3. 
Result so far: 147002.6303
Deduct 1047 from 1300 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 13:
349 goes into 2530 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 147002.63037
If we take 2443 away from 2530, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 14:
870 divided by 349 is 2 with a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 147002.630372
Deduct 698 from 870 and we're left 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.

Advancing to step 15:
When dividing 1720 by 349, we get 4 with a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 147002.6303724
Deduct 1396 from 1720 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 16:
The number 349 fits into 3240 9 times, leaving a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 147002.63037249
If we subtract 3141 from 3240, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

In conclusion, the division gives 147002.63037249 with a balance of 9.9e-08.
