Let's divide 21311217 by 386
Let's see how many times 386 fits into 21311217.

Step 1:
386 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 386

Going ahead to step 2:
If we divide 21 by 386, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 386

Step 3:
386 goes into 213 0 times with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 213, we get 213.
Bring next digit (1) of the dividend behind the 213 and repeat the process: 2131 / 386

On to step 4:
If we divide 2131 by 386, we get 5 and a remainder of 201.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 1930 from 2131 and we're left with 201.
Take the next digit (1) from the dividend and append it to 201, then repeat: 2011 / 386

Advancing to step 5:
386 goes into 2011 5 times with a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtract 1930 from 2011 to get 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 386

Going ahead to step 6:
386 goes into 812 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 552.0
If we subtract 772 from 812, we get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 386

Moving on to step 7:
386 goes into 401 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 5521.0
If we subtract 386 from 401, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 386

Step 8:
157 divided by 386 is 0 with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 55210.0
If we subtract 0 from 157, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
1570 divided by 386 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 55210.4
Subtracting 1544 from 1570 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
The number 386 fits into 260 0 times, leaving a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 55210.4
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
If we divide 2600 by 386, we get 6 and a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 55210.406
Subtract 2316 from 2600 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 12:
When dividing 2840 by 386, we get 7 with a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 55210.4067
Subtracting 2702 from 2840 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 13:
The number 386 fits into 1380 3 times, leaving a remainder of 222.
Put 3 as the next digit of the answer. 
Result so far: 55210.40673
Deduct 1158 from 1380 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 14:
386 goes into 2220 5 times with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 55210.406735
If we take 1930 away from 2220, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 15:
386 can be fit into 2900 7 times, resulting in a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 55210.4067357
Deduct 2702 from 2900 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 16:
When dividing 1980 by 386, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 55210.40673575
If we subtract 1930 from 1980, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 55210.40673575, and the remainder is 5e-08.
