We're dividing 63089943 by 386 
We want to figure out the number of times 63089943 can be divided by 386.

Step 1:
386 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 386

Moving on to step 2:
When dividing 63 by 386, we get 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 386

Going ahead to step 3:
When dividing 630 by 386, we get 1 with a remainder of 244.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 386 away from 630, we end up with 244.
Include the next digit (8) from the dividend after 244, then repeat: 2448 / 386

Step 4:
If we divide 2448 by 386, we get 6 and a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2316 from 2448 and we're left with 132.
Include the next digit (9) from the dividend after 132, then repeat: 1329 / 386

Moving on to step 5:
1329 divided by 386 is 3 with a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 171 after subtracting 1158 from 1329.
Append the next digit (9) from the dividend to 171 and continue with: 1719 / 386

Advancing to step 6:
1719 divided by 386 is 4 with a remainder of 175.
Use 4 as the next digit of our solution. 
Result so far: 1634.0
Deduct 1544 from 1719 and we're left with 175.
Bring next digit (4) of the dividend behind the 175 and repeat the process: 1754 / 386

Advancing to step 7:
386 goes into 1754 4 times with a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 16344.0
Deduct 1544 from 1754 and we're left with 210.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 386

Step 8:
If we divide 2103 by 386, we get 5 and a remainder of 173.
Use 5 as the next digit of our solution. 
Result so far: 163445.0
The remainder is 173 after subtracting 1930 from 2103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

On to step 9:
1730 divided by 386 is 4 with a remainder of 186.
Record the quotient 4 as the next digit in the result. 
Result so far: 163445.4
Subtract 1544 from 1730 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
386 can be fit into 1860 4 times, resulting in a remainder of 316.
The next digit of our result is 4. 
Result so far: 163445.44
Subtracting 1544 from 1860 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final outcome is 163445.44, with a leftover of 0.316.
