We look at the division of 30429407 by 660 
We want to divide 30429407 by 660.

Going ahead to step 1:
When dividing 3 by 660, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 660

Step 2:
When dividing 30 by 660, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 660

Advancing to step 3:
660 can be fit into 304 0 times, resulting in a remainder of 304.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 304, we end up with 304.
Append the next digit (2) from the dividend to 304 and continue with: 3042 / 660

Let's proceed to step 4:
When dividing 3042 by 660, we get 4 with a remainder of 402.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2640 from 3042, we get 402.
Grab the next digit (9) from the dividend, add it to 402, then carry on: 4029 / 660

Moving on to step 5:
The number 660 fits into 4029 6 times, leaving a remainder of 69.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 3960 from 4029 leaves us with 69.
Grab the next digit (4) from the dividend, add it to 69, then carry on: 694 / 660

Moving on to step 6:
If we divide 694 by 660, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
The remainder is 34 after subtracting 660 from 694.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 660

On to step 7:
When dividing 340 by 660, we get 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 4610.0
The remainder is 340 after subtracting 0 from 340.
Append the next digit (7) from the dividend to 340 and continue with: 3407 / 660

Going ahead to step 8:
When dividing 3407 by 660, we get 5 with a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 46105.0
If we subtract 3300 from 3407, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
660 goes into 1070 1 times with a remainder of 410.
The next digit of our result is 1. 
Result so far: 46105.1
If we take 660 away from 1070, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 10:
660 can be fit into 4100 6 times, resulting in a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 46105.16
Subtract 3960 from 4100 to get 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 11:
If we divide 1400 by 660, we get 2 and a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 46105.162
Deduct 1320 from 1400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
When dividing 800 by 660, we get 1 with a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 46105.1621
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
1400 divided by 660 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 46105.16212
Subtract 1320 from 1400 to 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.

Going ahead to step 14:
If we divide 800 by 660, we get 1 and a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 46105.162121
Subtracting 660 from 800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
When dividing 1400 by 660, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 46105.1621212
Deduct 1320 from 1400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
660 can be fit into 800 1 times, resulting in a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 46105.16212121
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 46105.16212121 with a remaining 1.4e-07.
