We divide 393487 by 99
Our goal is to divide 393487 by 99.

On to step 1:
3 divided by 99 is 0 with 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 (9) from the dividend and append it to 3, then repeat: 39 / 99

Going ahead to step 2:
39 divided by 99 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 99

On to step 3:
If we divide 393 by 99, we get 3 and a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 96 after subtracting 297 from 393.
Bring next digit (4) of the dividend behind the 96 and repeat the process: 964 / 99

Step 4:
When dividing 964 by 99, we get 9 with a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 891 away from 964, we end up with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 99

Let's proceed to step 5:
738 divided by 99 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 397.0
Deduct 693 from 738 and we're left with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 99

Step 6:
If we divide 457 by 99, we get 4 and a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 3974.0
Subtracting 396 from 457 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
99 goes into 610 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3974.6
The remainder is 16 after subtracting 594 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
99 goes into 160 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 3974.61
If we subtract 99 from 160, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
99 goes into 610 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3974.616
Subtracting 594 from 610 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 99 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 3974.6161
The remainder is 61 after subtracting 99 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 11:
99 goes into 610 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 3974.61616
Deduct 594 from 610 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 99, we get 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 3974.616161
Deduct 99 from 160 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 13:
99 can be fit into 610 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 3974.6161616
Subtracting 594 from 610 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
99 goes into 160 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 3974.61616161
The remainder is 61 after subtracting 99 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 3974.61616161 with a remaining 6.1e-08.
