Let's divide 66249983 by 393
We want to divide 66249983 by 393.

On to step 1:
If we divide 6 by 393, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 393

Moving on to step 2:
When dividing 66 by 393, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 393

Moving on to step 3:
If we divide 662 by 393, we get 1 and a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 393 from 662 to get 269.
Take the next digit (4) from the dividend and append it to 269, then repeat: 2694 / 393

On to step 4:
The number 393 fits into 2694 6 times, leaving a remainder of 336.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2358 from 2694 to get 336.
Grab the next digit (9) from the dividend, add it to 336, then carry on: 3369 / 393

On to step 5:
If we divide 3369 by 393, we get 8 and a remainder of 225.
Write down 8 as next digit of the result. 
Result so far: 168.0
The remainder is 225 after subtracting 3144 from 3369.
Grab the next digit (9) from the dividend, add it to 225, then carry on: 2259 / 393

Moving on to step 6:
If we divide 2259 by 393, we get 5 and a remainder of 294.
Write down 5 as next digit of the result. 
Result so far: 1685.0
The remainder is 294 after subtracting 1965 from 2259.
Grab the next digit (8) from the dividend, add it to 294, then carry on: 2948 / 393

Step 7:
393 can be fit into 2948 7 times, resulting in a remainder of 197.
Put 7 as the next digit of the answer. 
Result so far: 16857.0
Subtract 2751 from 2948 to get 197.
Fetch the next digit (3) from the dividend, attach it to 197 and continue: 1973 / 393

On to step 8:
393 can be fit into 1973 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 168575.0
If we subtract 1965 from 1973, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 393 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 168575.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
800 divided by 393 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 168575.02
Subtract 786 from 800 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 393, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 168575.02
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 393 is 3 with a remainder of 221.
Put 3 as the next digit of the answer. 
Result so far: 168575.0203
Subtracting 1179 from 1400 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 13:
When dividing 2210 by 393, we get 5 with a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 168575.02035
Subtract 1965 from 2210 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 14:
When dividing 2450 by 393, we get 6 with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 168575.020356
Subtracting 2358 from 2450 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 15:
The number 393 fits into 920 2 times, leaving a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 168575.0203562
Deduct 786 from 920 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 16:
If we divide 1340 by 393, we get 3 and a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 168575.02035623
Subtract 1179 from 1340 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Our division results in 168575.02035623 with a remaining 1.61e-07.
