We look at the division of 66574920 by 435 
We want to divide 66574920 by 435.

Moving on to step 1:
435 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
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 / 435

Advancing to step 2:
435 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 435

Going ahead to step 3:
The number 435 fits into 665 1 times, leaving a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 435 away from 665, we end up with 230.
Grab the next digit (7) from the dividend, add it to 230, then carry on: 2307 / 435

Going ahead to step 4:
2307 divided by 435 is 5 with a remainder of 132.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2175 from 2307 leaves us with 132.
Fetch the next digit (4) from the dividend, attach it to 132 and continue: 1324 / 435

Advancing to step 5:
The number 435 fits into 1324 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
If we subtract 1305 from 1324, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 435

Going ahead to step 6:
199 divided by 435 is 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 1530.0
If we take 0 away from 199, we end up with 199.
Include the next digit (2) from the dividend after 199, then repeat: 1992 / 435

Step 7:
The number 435 fits into 1992 4 times, leaving a remainder of 252.
Write down 4 as next digit of the result. 
Result so far: 15304.0
Subtracting 1740 from 1992 leaves us with 252.
Include the next digit (0) from the dividend after 252, then repeat: 2520 / 435

Moving on to step 8:
The number 435 fits into 2520 5 times, leaving a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 153045.0
Subtract 2175 from 2520 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 9:
The number 435 fits into 3450 7 times, leaving a remainder of 405.
Record the quotient 7 as the next digit in the result. 
Result so far: 153045.7
Deduct 3045 from 3450 and we're left with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 10:
When dividing 4050 by 435, we get 9 with a remainder of 135.
Put 9 as the next digit of the answer. 
Result so far: 153045.79
Subtract 3915 from 4050 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
When dividing 1350 by 435, we get 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 153045.793
Subtracting 1305 from 1350 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
If we divide 450 by 435, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 153045.7931
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
The number 435 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 153045.7931
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 14:
If we divide 1500 by 435, we get 3 and a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 153045.793103
Deduct 1305 from 1500 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 15:
435 can be fit into 1950 4 times, resulting in a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 153045.7931034
Subtract 1740 from 1950 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 16:
435 can be fit into 2100 4 times, resulting in a remainder of 360.
The next digit of our result is 4. 
Result so far: 153045.79310344
Deduct 1740 from 2100 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 153045.79310344 with a balance of 3.6e-07.
