13987007 divided by 349 
We're looking to find how many times 349 goes into 13987007.

Let's proceed to step 1:
349 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 349

Step 2:
13 divided by 349 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 349

Advancing to step 3:
If we divide 139 by 349, we get 0 and a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 139 after subtracting 0 from 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 349

Moving on to step 4:
The number 349 fits into 1398 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1396 from 1398 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 349

Advancing to step 5:
349 goes into 27 0 times with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 349

Going ahead to step 6:
If we divide 270 by 349, we get 0 and a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Subtract 0 from 270 to get 270.
Fetch the next digit (0) from the dividend, attach it to 270 and continue: 2700 / 349

Advancing to step 7:
2700 divided by 349 is 7 with a remainder of 257.
Record the quotient 7 as the next digit in the result. 
Result so far: 4007.0
If we subtract 2443 from 2700, we get 257.
Grab the next digit (7) from the dividend, add it to 257, then carry on: 2577 / 349

Advancing to step 8:
2577 divided by 349 is 7 with a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 40077.0
If we take 2443 away from 2577, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
The number 349 fits into 1340 3 times, leaving a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 40077.3
Subtracting 1047 from 1340 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 10:
The number 349 fits into 2930 8 times, leaving a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 40077.38
Subtract 2792 from 2930 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 11:
The number 349 fits into 1380 3 times, leaving a remainder of 333.
The next digit of our result is 3. 
Result so far: 40077.383
If we subtract 1047 from 1380, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Let's proceed to step 12:
When dividing 3330 by 349, we get 9 with a remainder of 189.
The next digit of our result is 9. 
Result so far: 40077.3839
If we take 3141 away from 3330, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 13:
If we divide 1890 by 349, we get 5 and a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 40077.38395
If we subtract 1745 from 1890, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 14:
1450 divided by 349 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 40077.383954
The remainder is 54 after subtracting 1396 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 15:
The number 349 fits into 540 1 times, leaving a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 40077.3839541
Deduct 349 from 540 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 16:
The number 349 fits into 1910 5 times, leaving a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 40077.38395415
Deduct 1745 from 1910 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 40077.38395415 with a remainder of 1.65e-07.
