We look at the division of 37399 by 66 
Our goal is to divide 37399 by 66.

On to step 1:
3 divided by 66 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 66

On to step 2:
When dividing 37 by 66, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 66

Advancing to step 3:
66 goes into 373 5 times with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 43 after subtracting 330 from 373.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 66

Step 4:
439 divided by 66 is 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtract 396 from 439 to get 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 66

Going ahead to step 5:
439 divided by 66 is 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
If we take 396 away from 439, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 6:
When dividing 430 by 66, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 566.6
The remainder is 34 after subtracting 396 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 66, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 566.65
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
66 goes into 100 1 times with a remainder of 34.
The next digit of our result is 1. 
Result so far: 566.651
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 66, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 566.6515
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 566.65151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
When dividing 340 by 66, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 566.651515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
66 goes into 100 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 566.6515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
If we divide 340 by 66, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 566.65151515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 566.65151515, and the remainder is 1e-08.
