We divide 15686290 by 386
Our goal is to divide 15686290 by 386.

Moving on to step 1:
The number 386 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 386

Step 2:
386 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 386

On to step 3:
386 can be fit into 156 0 times, resulting in a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Bring next digit (8) of the dividend behind the 156 and repeat the process: 1568 / 386

Moving on to step 4:
When dividing 1568 by 386, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1544 from 1568 to get 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 386

Let's proceed to step 5:
246 divided by 386 is 0 with a remainder of 246.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 246, we get 246.
Take the next digit (2) from the dividend and append it to 246, then repeat: 2462 / 386

Going ahead to step 6:
386 can be fit into 2462 6 times, resulting in a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 406.0
Subtract 2316 from 2462 to get 146.
Fetch the next digit (9) from the dividend, attach it to 146 and continue: 1469 / 386

Let's proceed to step 7:
If we divide 1469 by 386, we get 3 and a remainder of 311.
The number 3 becomes the next digit in our result. 
Result so far: 4063.0
Deduct 1158 from 1469 and we're left with 311.
Bring next digit (0) of the dividend behind the 311 and repeat the process: 3110 / 386

Advancing to step 8:
386 goes into 3110 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 40638.0
Subtracting 3088 from 3110 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
386 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 40638.0
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
386 goes into 2200 5 times with a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 40638.05
Subtracting 1930 from 2200 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
386 goes into 2700 6 times with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 40638.056
If we take 2316 away from 2700, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 12:
3840 divided by 386 is 9 with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 40638.0569
The remainder is 366 after subtracting 3474 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 13:
3660 divided by 386 is 9 with a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 40638.05699
The remainder is 186 after subtracting 3474 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final outcome is 40638.05699, with a leftover of 0.000186.
