15186686 ÷ 740 
We're looking to find how many times 740 goes into 15186686.

Step 1:
The number 740 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 740

On to step 2:
740 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 740

On to step 3:
The number 740 fits into 151 0 times, leaving a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Append the next digit (8) from the dividend to 151 and continue with: 1518 / 740

Going ahead to step 4:
The number 740 fits into 1518 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 38 after subtracting 1480 from 1518.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 740

Let's proceed to step 5:
740 can be fit into 386 0 times, resulting in a remainder of 386.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 386, we end up with 386.
Grab the next digit (6) from the dividend, add it to 386, then carry on: 3866 / 740

Moving on to step 6:
740 goes into 3866 5 times with a remainder of 166.
The next digit of our result is 5. 
Result so far: 205.0
Subtracting 3700 from 3866 leaves us with 166.
Grab the next digit (8) from the dividend, add it to 166, then carry on: 1668 / 740

Let's proceed to step 7:
When dividing 1668 by 740, we get 2 with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 2052.0
The remainder is 188 after subtracting 1480 from 1668.
Grab the next digit (6) from the dividend, add it to 188, then carry on: 1886 / 740

Going ahead to step 8:
The number 740 fits into 1886 2 times, leaving a remainder of 406.
Record the quotient 2 as the next digit in the result. 
Result so far: 20522.0
If we take 1480 away from 1886, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 9:
The number 740 fits into 4060 5 times, leaving a remainder of 360.
The next digit of our result is 5. 
Result so far: 20522.5
Subtracting 3700 from 4060 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
The number 740 fits into 3600 4 times, leaving a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 20522.54
If we subtract 2960 from 3600, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
If we divide 6400 by 740, we get 8 and a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 20522.548
Subtract 5920 from 6400 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
740 goes into 4800 6 times with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 20522.5486
Subtracting 4440 from 4800 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
The number 740 fits into 3600 4 times, leaving a remainder of 640.
Use 4 as the next digit of our solution. 
Result so far: 20522.54864
If we take 2960 away from 3600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
The number 740 fits into 6400 8 times, leaving a remainder of 480.
The next digit of our result is 8. 
Result so far: 20522.548648
Deduct 5920 from 6400 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 15:
740 can be fit into 4800 6 times, resulting in a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 20522.5486486
Subtracting 4440 from 4800 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
If we divide 3600 by 740, we get 4 and a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 20522.54864864
The remainder is 640 after subtracting 2960 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 20522.54864864, with a leftover of 6.4e-07.
