We're dividing 66433755 by 430 
Our goal is to divide 66433755 by 430.

Step 1:
The number 430 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 430

On to step 2:
The number 430 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 430

Advancing to step 3:
430 can be fit into 664 1 times, resulting in a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 430 from 664 leaves us with 234.
Take the next digit (3) from the dividend and append it to 234, then repeat: 2343 / 430

Moving on to step 4:
430 can be fit into 2343 5 times, resulting in a remainder of 193.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2150 from 2343 to get 193.
Append the next digit (3) from the dividend to 193 and continue with: 1933 / 430

On to step 5:
When dividing 1933 by 430, we get 4 with a remainder of 213.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Deduct 1720 from 1933 and we're left with 213.
Append the next digit (7) from the dividend to 213 and continue with: 2137 / 430

Moving on to step 6:
2137 divided by 430 is 4 with a remainder of 417.
Record the quotient 4 as the next digit in the result. 
Result so far: 1544.0
Subtracting 1720 from 2137 leaves us with 417.
Include the next digit (5) from the dividend after 417, then repeat: 4175 / 430

Moving on to step 7:
If we divide 4175 by 430, we get 9 and a remainder of 305.
Put 9 as the next digit of the answer. 
Result so far: 15449.0
The remainder is 305 after subtracting 3870 from 4175.
Append the next digit (5) from the dividend to 305 and continue with: 3055 / 430

On to step 8:
When dividing 3055 by 430, we get 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 154497.0
Subtracting 3010 from 3055 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.

On to step 9:
430 can be fit into 450 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 154497.1
Subtract 430 from 450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
430 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 154497.1
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
If we divide 2000 by 430, we get 4 and a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 154497.104
Subtracting 1720 from 2000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
430 can be fit into 2800 6 times, resulting in a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 154497.1046
Deduct 2580 from 2800 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
430 goes into 2200 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 154497.10465
Deduct 2150 from 2200 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
The number 430 fits into 500 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 154497.104651
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 15:
If we divide 700 by 430, we get 1 and a remainder of 270.
The number 1 becomes the next digit in our result. 
Result so far: 154497.1046511
The remainder is 270 after subtracting 430 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 154497.1046511 with a remainder of 2.7e-06.
