We divide 66831790 by 510
We want to divide 66831790 by 510.

On to step 1:
510 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 510

Going ahead to step 2:
If we divide 66 by 510, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 510

Let's proceed to step 3:
If we divide 668 by 510, we get 1 and a remainder of 158.
The next digit of our result is 1. 
Result so far: 1.0
If we take 510 away from 668, we end up with 158.
Grab the next digit (3) from the dividend, add it to 158, then carry on: 1583 / 510

On to step 4:
When dividing 1583 by 510, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 53 after subtracting 1530 from 1583.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 510

Advancing to step 5:
The number 510 fits into 531 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 131.0
Subtract 510 from 531 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 510

Moving on to step 6:
When dividing 217 by 510, we get 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 1310.0
If we subtract 0 from 217, we get 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 510

Let's proceed to step 7:
510 can be fit into 2179 4 times, resulting in a remainder of 139.
Record the quotient 4 as the next digit in the result. 
Result so far: 13104.0
Deduct 2040 from 2179 and we're left with 139.
Grab the next digit (0) from the dividend, add it to 139, then carry on: 1390 / 510

Advancing to step 8:
When dividing 1390 by 510, we get 2 with a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 131042.0
Subtracting 1020 from 1390 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
510 can be fit into 3700 7 times, resulting in a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 131042.7
Subtract 3570 from 3700 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
1300 divided by 510 is 2 with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 131042.72
If we take 1020 away from 1300, we end up 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 11:
510 goes into 2800 5 times with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 131042.725
Subtract 2550 from 2800 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
The number 510 fits into 2500 4 times, leaving a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 131042.7254
Subtract 2040 from 2500 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 13:
If we divide 4600 by 510, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 131042.72549
Subtracting 4590 from 4600 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.

Step 14:
If we divide 100 by 510, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 131042.72549
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
1000 divided by 510 is 1 with a remainder of 490.
Write down 1 as next digit of the result. 
Result so far: 131042.7254901
Subtracting 510 from 1000 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 16:
510 can be fit into 4900 9 times, resulting in a remainder of 310.
Write down 9 as next digit of the result. 
Result so far: 131042.72549019
Subtract 4590 from 4900 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 131042.72549019 with a balance of 3.1e-07.
