We look at the division of 66458410 by 474 
Our goal is to divide 66458410 by 474.

On to step 1:
474 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 474

Going ahead to step 2:
If we divide 66 by 474, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 474

Step 3:
474 goes into 664 1 times with a remainder of 190.
The next digit of our result is 1. 
Result so far: 1.0
If we take 474 away from 664, we end up with 190.
Grab the next digit (5) from the dividend, add it to 190, then carry on: 1905 / 474

Advancing to step 4:
If we divide 1905 by 474, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1896 away from 1905, we end up with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 474

Moving on to step 5:
The number 474 fits into 98 0 times, leaving a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we take 0 away from 98, we end up with 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 474

On to step 6:
If we divide 984 by 474, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 1402.0
Subtract 948 from 984 to get 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 474

Going ahead to step 7:
When dividing 361 by 474, we get 0 with a remainder of 361.
Use 0 as the next digit of our solution. 
Result so far: 14020.0
If we subtract 0 from 361, we get 361.
Append the next digit (0) from the dividend to 361 and continue with: 3610 / 474

Let's proceed to step 8:
The number 474 fits into 3610 7 times, leaving a remainder of 292.
Write down 7 as next digit of the result. 
Result so far: 140207.0
Subtracting 3318 from 3610 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 9:
2920 divided by 474 is 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 140207.6
The remainder is 76 after subtracting 2844 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
474 goes into 760 1 times with a remainder of 286.
Record the quotient 1 as the next digit in the result. 
Result so far: 140207.61
Subtract 474 from 760 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 11:
The number 474 fits into 2860 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 140207.616
Deduct 2844 from 2860 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:
If we divide 160 by 474, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 140207.616
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
If we divide 1600 by 474, we get 3 and a remainder of 178.
Put 3 as the next digit of the answer. 
Result so far: 140207.61603
If we subtract 1422 from 1600, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 14:
1780 divided by 474 is 3 with a remainder of 358.
The next digit of our result is 3. 
Result so far: 140207.616033
If we subtract 1422 from 1780, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

The final result is 140207.616033 with a remainder of 3.58e-05.
