66157235 divided by 390 
We want to divide 66157235 by 390.

Advancing to step 1:
390 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
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 390

On to step 2:
The number 390 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 (1) from the dividend after 66, then repeat: 661 / 390

Step 3:
661 divided by 390 is 1 with a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 390 from 661, we get 271.
Take the next digit (5) from the dividend and append it to 271, then repeat: 2715 / 390

On to step 4:
If we divide 2715 by 390, we get 6 and a remainder of 375.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2340 from 2715 and we're left with 375.
Take the next digit (7) from the dividend and append it to 375, then repeat: 3757 / 390

Advancing to step 5:
When dividing 3757 by 390, we get 9 with a remainder of 247.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 247 after subtracting 3510 from 3757.
Include the next digit (2) from the dividend after 247, then repeat: 2472 / 390

Going ahead to step 6:
If we divide 2472 by 390, we get 6 and a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 1696.0
Subtract 2340 from 2472 to get 132.
Append the next digit (3) from the dividend to 132 and continue with: 1323 / 390

Step 7:
390 can be fit into 1323 3 times, resulting in a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 16963.0
If we take 1170 away from 1323, we end up with 153.
Take the next digit (5) from the dividend and append it to 153, then repeat: 1535 / 390

Going ahead to step 8:
390 goes into 1535 3 times with a remainder of 365.
Record the quotient 3 as the next digit in the result. 
Result so far: 169633.0
Subtracting 1170 from 1535 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 9:
3650 divided by 390 is 9 with a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 169633.9
If we take 3510 away from 3650, 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.

On to step 10:
1400 divided by 390 is 3 with a remainder of 230.
Write down 3 as next digit of the result. 
Result so far: 169633.93
Subtracting 1170 from 1400 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 11:
When dividing 2300 by 390, we get 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 169633.935
If we take 1950 away from 2300, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
The number 390 fits into 3500 8 times, leaving a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 169633.9358
If we take 3120 away from 3500, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 13:
If we divide 3800 by 390, we get 9 and a remainder of 290.
The next digit of our result is 9. 
Result so far: 169633.93589
The remainder is 290 after subtracting 3510 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
2900 divided by 390 is 7 with a remainder of 170.
The number 7 becomes the next digit in our result. 
Result so far: 169633.935897
If we take 2730 away from 2900, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
When dividing 1700 by 390, we get 4 with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 169633.9358974
Subtract 1560 from 1700 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 16:
390 can be fit into 1400 3 times, resulting in a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 169633.93589743
If we take 1170 away from 1400, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

In conclusion, the division gives 169633.93589743 with a balance of 2.3e-07.
