64731561 ÷ 386 
Our goal is to divide 64731561 by 386.

Going ahead to step 1:
When dividing 6 by 386, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 386

Advancing to step 2:
If we divide 64 by 386, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 386

Advancing to step 3:
The number 386 fits into 647 1 times, leaving a remainder of 261.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 386 from 647 to get 261.
Take the next digit (3) from the dividend and append it to 261, then repeat: 2613 / 386

Step 4:
The number 386 fits into 2613 6 times, leaving a remainder of 297.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 2316 from 2613, we get 297.
Bring next digit (1) of the dividend behind the 297 and repeat the process: 2971 / 386

Advancing to step 5:
386 can be fit into 2971 7 times, resulting in a remainder of 269.
Write down 7 as next digit of the result. 
Result so far: 167.0
The remainder is 269 after subtracting 2702 from 2971.
Fetch the next digit (5) from the dividend, attach it to 269 and continue: 2695 / 386

Let's proceed to step 6:
If we divide 2695 by 386, we get 6 and a remainder of 379.
Put 6 as the next digit of the answer. 
Result so far: 1676.0
Subtract 2316 from 2695 to get 379.
Include the next digit (6) from the dividend after 379, then repeat: 3796 / 386

Let's proceed to step 7:
386 can be fit into 3796 9 times, resulting in a remainder of 322.
Record the quotient 9 as the next digit in the result. 
Result so far: 16769.0
Deduct 3474 from 3796 and we're left with 322.
Bring next digit (1) of the dividend behind the 322 and repeat the process: 3221 / 386

Let's proceed to step 8:
If we divide 3221 by 386, we get 8 and a remainder of 133.
The number 8 becomes the next digit in our result. 
Result so far: 167698.0
Subtract 3088 from 3221 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
If we divide 1330 by 386, we get 3 and a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 167698.3
Subtracting 1158 from 1330 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 10:
When dividing 1720 by 386, we get 4 with a remainder of 176.
The next digit of our result is 4. 
Result so far: 167698.34
Subtract 1544 from 1720 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
1760 divided by 386 is 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 167698.344
The remainder is 216 after subtracting 1544 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final result is 167698.344 with a remainder of 0.0216.
