We're dividing 66859029 by 990 
We're looking to find how many times 990 goes into 66859029.

Advancing to step 1:
The number 990 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
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 990

Going ahead to step 2:
The number 990 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
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 990

Step 3:
668 divided by 990 is 0 with a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 668 leaves us with 668.
Grab the next digit (5) from the dividend, add it to 668, then carry on: 6685 / 990

Going ahead to step 4:
The number 990 fits into 6685 6 times, leaving a remainder of 745.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 5940 from 6685, we get 745.
Take the next digit (9) from the dividend and append it to 745, then repeat: 7459 / 990

Moving on to step 5:
990 goes into 7459 7 times with a remainder of 529.
The next digit of our result is 7. 
Result so far: 67.0
Subtract 6930 from 7459 to get 529.
Bring next digit (0) of the dividend behind the 529 and repeat the process: 5290 / 990

Step 6:
When dividing 5290 by 990, we get 5 with a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 675.0
Deduct 4950 from 5290 and we're left with 340.
Fetch the next digit (2) from the dividend, attach it to 340 and continue: 3402 / 990

Step 7:
990 goes into 3402 3 times with a remainder of 432.
The next digit of our result is 3. 
Result so far: 6753.0
If we take 2970 away from 3402, we end up with 432.
Append the next digit (9) from the dividend to 432 and continue with: 4329 / 990

Advancing to step 8:
The number 990 fits into 4329 4 times, leaving a remainder of 369.
Use 4 as the next digit of our solution. 
Result so far: 67534.0
Deduct 3960 from 4329 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 9:
990 goes into 3690 3 times with a remainder of 720.
Put 3 as the next digit of the answer. 
Result so far: 67534.3
Subtracting 2970 from 3690 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 10:
If we divide 7200 by 990, we get 7 and a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 67534.37
Subtracting 6930 from 7200 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 11:
2700 divided by 990 is 2 with a remainder of 720.
The next digit of our result is 2. 
Result so far: 67534.372
The remainder is 720 after subtracting 1980 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 12:
990 goes into 7200 7 times with a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 67534.3727
If we take 6930 away from 7200, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 13:
990 can be fit into 2700 2 times, resulting in a remainder of 720.
Put 2 as the next digit of the answer. 
Result so far: 67534.37272
Deduct 1980 from 2700 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 14:
990 can be fit into 7200 7 times, resulting in a remainder of 270.
The number 7 becomes the next digit in our result. 
Result so far: 67534.372727
If we take 6930 away from 7200, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 15:
990 can be fit into 2700 2 times, resulting in a remainder of 720.
The next digit of our result is 2. 
Result so far: 67534.3727272
Subtracting 1980 from 2700 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 16:
990 goes into 7200 7 times with a remainder of 270.
The next digit of our result is 7. 
Result so far: 67534.37272727
Subtracting 6930 from 7200 leaves us with 270.
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 outcome is 67534.37272727, with a leftover of 2.7e-07.
