Let's divide 51705290 by 349
Our goal is to divide 51705290 by 349.

Moving on to step 1:
If we divide 5 by 349, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 349

Going ahead to step 2:
The number 349 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 349

Step 3:
The number 349 fits into 517 1 times, leaving a remainder of 168.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 349 from 517, we get 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 349

Advancing to step 4:
If we divide 1680 by 349, we get 4 and a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 1396 from 1680 leaves us with 284.
Include the next digit (5) from the dividend after 284, then repeat: 2845 / 349

Advancing to step 5:
The number 349 fits into 2845 8 times, leaving a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we subtract 2792 from 2845, we get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 349

Going ahead to step 6:
If we divide 532 by 349, we get 1 and a remainder of 183.
Write down 1 as next digit of the result. 
Result so far: 1481.0
If we subtract 349 from 532, we get 183.
Include the next digit (9) from the dividend after 183, then repeat: 1839 / 349

Going ahead to step 7:
1839 divided by 349 is 5 with a remainder of 94.
Put 5 as the next digit of the answer. 
Result so far: 14815.0
If we take 1745 away from 1839, we end up with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 349

Moving on to step 8:
349 can be fit into 940 2 times, resulting in a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 148152.0
Subtracting 698 from 940 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 9:
349 goes into 2420 6 times with a remainder of 326.
Use 6 as the next digit of our solution. 
Result so far: 148152.6
Subtracting 2094 from 2420 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
If we divide 3260 by 349, we get 9 and a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 148152.69
Deduct 3141 from 3260 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 11:
If we divide 1190 by 349, we get 3 and a remainder of 143.
The next digit of our result is 3. 
Result so far: 148152.693
If we subtract 1047 from 1190, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 12:
If we divide 1430 by 349, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 148152.6934
Subtracting 1396 from 1430 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
340 divided by 349 is 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 148152.6934
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
349 goes into 3400 9 times with a remainder of 259.
The next digit of our result is 9. 
Result so far: 148152.693409
Subtracting 3141 from 3400 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 15:
349 can be fit into 2590 7 times, resulting in a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 148152.6934097
Deduct 2443 from 2590 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 16:
349 can be fit into 1470 4 times, resulting in a remainder of 74.
The next digit of our result is 4. 
Result so far: 148152.69340974
The remainder is 74 after subtracting 1396 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 148152.69340974, with a leftover of 7.4e-08.
