66977162 divided by 351 
We want to figure out the number of times 66977162 can be divided by 351.

On to step 1:
6 divided by 351 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 351

Going ahead to step 2:
The number 351 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 351

Let's proceed to step 3:
351 goes into 669 1 times with a remainder of 318.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 351 from 669 to get 318.
Take the next digit (7) from the dividend and append it to 318, then repeat: 3187 / 351

On to step 4:
If we divide 3187 by 351, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 3159 from 3187 leaves us with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 351

On to step 5:
The number 351 fits into 287 0 times, leaving a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 287 to get 287.
Include the next digit (1) from the dividend after 287, then repeat: 2871 / 351

On to step 6:
If we divide 2871 by 351, we get 8 and a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 1908.0
Subtracting 2808 from 2871 leaves us with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 351

Going ahead to step 7:
When dividing 636 by 351, we get 1 with a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 19081.0
Subtracting 351 from 636 leaves us with 285.
Include the next digit (2) from the dividend after 285, then repeat: 2852 / 351

Moving on to step 8:
2852 divided by 351 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 190818.0
If we take 2808 away from 2852, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 351, we get 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 190818.1
If we take 351 away from 440, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 10:
When dividing 890 by 351, we get 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 190818.12
The remainder is 188 after subtracting 702 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
When dividing 1880 by 351, we get 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 190818.125
Subtract 1755 from 1880 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
The number 351 fits into 1250 3 times, leaving a remainder of 197.
Use 3 as the next digit of our solution. 
Result so far: 190818.1253
Subtracting 1053 from 1250 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 13:
When dividing 1970 by 351, we get 5 with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 190818.12535
Subtracting 1755 from 1970 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 14:
If we divide 2150 by 351, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 190818.125356
Deduct 2106 from 2150 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
If we divide 440 by 351, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 190818.1253561
Subtract 351 from 440 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 16:
If we divide 890 by 351, we get 2 and a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 190818.12535612
Deduct 702 from 890 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

In conclusion, the division gives 190818.12535612 with a balance of 1.88e-07.
