We look at the division of 31628686 by 386 
Our goal is to divide 31628686 by 386.

Step 1:
386 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 386

On to step 2:
31 divided by 386 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 386

Step 3:
386 can be fit into 316 0 times, resulting in a remainder of 316.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 316, we get 316.
Grab the next digit (2) from the dividend, add it to 316, then carry on: 3162 / 386

Step 4:
386 can be fit into 3162 8 times, resulting in a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 3088 from 3162, we get 74.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 386

Moving on to step 5:
If we divide 748 by 386, we get 1 and a remainder of 362.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 362 after subtracting 386 from 748.
Grab the next digit (6) from the dividend, add it to 362, then carry on: 3626 / 386

Advancing to step 6:
The number 386 fits into 3626 9 times, leaving a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 819.0
The remainder is 152 after subtracting 3474 from 3626.
Include the next digit (8) from the dividend after 152, then repeat: 1528 / 386

Step 7:
386 goes into 1528 3 times with a remainder of 370.
Write down 3 as next digit of the result. 
Result so far: 8193.0
Subtract 1158 from 1528 to get 370.
Grab the next digit (6) from the dividend, add it to 370, then carry on: 3706 / 386

Going ahead to step 8:
386 can be fit into 3706 9 times, resulting in a remainder of 232.
The next digit of our result is 9. 
Result so far: 81939.0
The remainder is 232 after subtracting 3474 from 3706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 9:
The number 386 fits into 2320 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 81939.6
The remainder is 4 after subtracting 2316 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
386 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 81939.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
When dividing 400 by 386, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 81939.601
If we take 386 away from 400, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
When dividing 140 by 386, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 81939.601
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
386 goes into 1400 3 times with a remainder of 242.
Record the quotient 3 as the next digit in the result. 
Result so far: 81939.60103
Deduct 1158 from 1400 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 14:
The number 386 fits into 2420 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 81939.601036
Subtract 2316 from 2420 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 15:
386 can be fit into 1040 2 times, resulting in a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 81939.6010362
If we subtract 772 from 1040, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 16:
2680 divided by 386 is 6 with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 81939.60103626
The remainder is 364 after subtracting 2316 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Our division results in 81939.60103626 with a remaining 3.64e-07.
