Let's divide 15129073 by 386
Let's see how many times 386 fits into 15129073.

On to step 1:
386 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 386

Let's proceed to step 2:
386 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 386

Step 3:
386 can be fit into 151 0 times, resulting in a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Grab the next digit (2) from the dividend, add it to 151, then carry on: 1512 / 386

On to step 4:
386 can be fit into 1512 3 times, resulting in a remainder of 354.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1158 away from 1512, we end up with 354.
Take the next digit (9) from the dividend and append it to 354, then repeat: 3549 / 386

Going ahead to step 5:
The number 386 fits into 3549 9 times, leaving a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 3474 from 3549, we get 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 386

Advancing to step 6:
386 can be fit into 750 1 times, resulting in a remainder of 364.
The next digit of our result is 1. 
Result so far: 391.0
If we take 386 away from 750, we end up with 364.
Include the next digit (7) from the dividend after 364, then repeat: 3647 / 386

Going ahead to step 7:
If we divide 3647 by 386, we get 9 and a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 3919.0
If we take 3474 away from 3647, we end up with 173.
Grab the next digit (3) from the dividend, add it to 173, then carry on: 1733 / 386

On to step 8:
386 can be fit into 1733 4 times, resulting in a remainder of 189.
Put 4 as the next digit of the answer. 
Result so far: 39194.0
If we take 1544 away from 1733, 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 9:
386 can be fit into 1890 4 times, resulting in a remainder of 346.
Put 4 as the next digit of the answer. 
Result so far: 39194.4
Subtract 1544 from 1890 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
The number 386 fits into 3460 8 times, leaving a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 39194.48
Subtract 3088 from 3460 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
If we divide 3720 by 386, we get 9 and a remainder of 246.
Put 9 as the next digit of the answer. 
Result so far: 39194.489
Deduct 3474 from 3720 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 12:
386 goes into 2460 6 times with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 39194.4896
If we subtract 2316 from 2460, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 13:
1440 divided by 386 is 3 with a remainder of 282.
The number 3 becomes the next digit in our result. 
Result so far: 39194.48963
If we take 1158 away from 1440, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 14:
If we divide 2820 by 386, we get 7 and a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 39194.489637
If we subtract 2702 from 2820, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 15:
386 goes into 1180 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 39194.4896373
The remainder is 22 after subtracting 1158 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
386 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 39194.4896373
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final result is 39194.4896373 with a remainder of 2.2e-07.
