If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 396

On to step 2:
396 goes into 61 0 times with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 396

Moving on to step 3:
The number 396 fits into 619 1 times, leaving a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 396 from 619 to get 223.
Bring next digit (3) of the dividend behind the 223 and repeat the process: 2233 / 396

On to step 4:
When dividing 2233 by 396, we get 5 with a remainder of 253.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 1980 from 2233 and we're left with 253.
Bring next digit (6) of the dividend behind the 253 and repeat the process: 2536 / 396

Step 5:
396 can be fit into 2536 6 times, resulting in a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtract 2376 from 2536 to get 160.
Append the next digit (8) from the dividend to 160 and continue with: 1608 / 396

Step 6:
1608 divided by 396 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1564.0
If we take 1584 away from 1608, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 396

Moving on to step 7:
396 goes into 243 0 times with a remainder of 243.
The next digit of our result is 0. 
Result so far: 15640.0
The remainder is 243 after subtracting 0 from 243.
Append the next digit (9) from the dividend to 243 and continue with: 2439 / 396

Going ahead to step 8:
2439 divided by 396 is 6 with a remainder of 63.
The next digit of our result is 6. 
Result so far: 156406.0
Subtract 2376 from 2439 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 9:
396 goes into 630 1 times with a remainder of 234.
Write down 1 as next digit of the result. 
Result so far: 156406.1
Subtract 396 from 630 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 10:
396 goes into 2340 5 times with a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 156406.15
Subtracting 1980 from 2340 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
396 can be fit into 3600 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 156406.159
The remainder is 36 after subtracting 3564 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
The number 396 fits into 360 0 times, leaving a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 156406.159
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 13:
When dividing 3600 by 396, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 156406.15909
Subtracting 3564 from 3600 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
396 goes into 360 0 times with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 156406.15909
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
The number 396 fits into 3600 9 times, leaving a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 156406.1590909
Deduct 3564 from 3600 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 16:
396 can be fit into 360 0 times, resulting in a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 156406.1590909
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 156406.1590909 with a remainder of 3.6e-07.
