51559316 ÷ 349 
We want to figure out the number of times 51559316 can be divided by 349.

Advancing to step 1:
When dividing 5 by 349, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 349

Advancing to step 2:
349 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 349

Let's proceed to step 3:
515 divided by 349 is 1 with a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 349 from 515 leaves us with 166.
Append the next digit (5) from the dividend to 166 and continue with: 1665 / 349

Let's proceed to step 4:
If we divide 1665 by 349, we get 4 and a remainder of 269.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 1396 away from 1665, we end up with 269.
Grab the next digit (9) from the dividend, add it to 269, then carry on: 2699 / 349

Going ahead to step 5:
2699 divided by 349 is 7 with a remainder of 256.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 2443 from 2699 and we're left with 256.
Include the next digit (3) from the dividend after 256, then repeat: 2563 / 349

Advancing to step 6:
349 can be fit into 2563 7 times, resulting in a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 1477.0
If we take 2443 away from 2563, we end up with 120.
Grab the next digit (1) from the dividend, add it to 120, then carry on: 1201 / 349

Advancing to step 7:
If we divide 1201 by 349, we get 3 and a remainder of 154.
Use 3 as the next digit of our solution. 
Result so far: 14773.0
Deduct 1047 from 1201 and we're left with 154.
Grab the next digit (6) from the dividend, add it to 154, then carry on: 1546 / 349

Going ahead to step 8:
349 goes into 1546 4 times with a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 147734.0
If we subtract 1396 from 1546, we 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.

Step 9:
349 can be fit into 1500 4 times, resulting in a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 147734.4
The remainder is 104 after subtracting 1396 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
349 can be fit into 1040 2 times, resulting in a remainder of 342.
Write down 2 as next digit of the result. 
Result so far: 147734.42
The remainder is 342 after subtracting 698 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 11:
The number 349 fits into 3420 9 times, leaving a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 147734.429
If we take 3141 away from 3420, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 12:
When dividing 2790 by 349, we get 7 with a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 147734.4297
If we take 2443 away from 2790, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 13:
349 can be fit into 3470 9 times, resulting in a remainder of 329.
The next digit of our result is 9. 
Result so far: 147734.42979
The remainder is 329 after subtracting 3141 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 14:
349 can be fit into 3290 9 times, resulting in a remainder of 149.
The next digit of our result is 9. 
Result so far: 147734.429799
Subtracting 3141 from 3290 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 147734.429799 with a remainder of 1.49e-05.
