78507519 ÷ 349 
We're looking to find how many times 349 goes into 78507519.

On to step 1:
When dividing 7 by 349, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 349

Let's proceed to step 2:
349 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 349

Advancing to step 3:
If we divide 785 by 349, we get 2 and a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 87 after subtracting 698 from 785.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 349

Step 4:
870 divided by 349 is 2 with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 172 after subtracting 698 from 870.
Take the next digit (7) from the dividend and append it to 172, then repeat: 1727 / 349

On to step 5:
349 can be fit into 1727 4 times, resulting in a remainder of 331.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
Subtract 1396 from 1727 to get 331.
Fetch the next digit (5) from the dividend, attach it to 331 and continue: 3315 / 349

Going ahead to step 6:
349 can be fit into 3315 9 times, resulting in a remainder of 174.
The next digit of our result is 9. 
Result so far: 2249.0
Deduct 3141 from 3315 and we're left with 174.
Append the next digit (1) from the dividend to 174 and continue with: 1741 / 349

On to step 7:
349 can be fit into 1741 4 times, resulting in a remainder of 345.
Record the quotient 4 as the next digit in the result. 
Result so far: 22494.0
The remainder is 345 after subtracting 1396 from 1741.
Include the next digit (9) from the dividend after 345, then repeat: 3459 / 349

Step 8:
When dividing 3459 by 349, we get 9 with a remainder of 318.
The next digit of our result is 9. 
Result so far: 224949.0
If we subtract 3141 from 3459, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
The number 349 fits into 3180 9 times, leaving a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 224949.9
Subtracting 3141 from 3180 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
349 can be fit into 390 1 times, resulting in a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 224949.91
Subtract 349 from 390 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 11:
349 can be fit into 410 1 times, resulting in a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 224949.911
The remainder is 61 after subtracting 349 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 224949.911 with a remainder of 0.0061.
