Let's divide 66309763 by 550
We want to figure out the number of times 66309763 can be divided by 550.

On to step 1:
550 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 550

Step 2:
When dividing 66 by 550, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 550

Step 3:
550 goes into 663 1 times with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 113 after subtracting 550 from 663.
Append the next digit (0) from the dividend to 113 and continue with: 1130 / 550

Going ahead to step 4:
1130 divided by 550 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1100 from 1130 and we're left with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 550

Advancing to step 5:
550 goes into 309 0 times with a remainder of 309.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 309 to get 309.
Append the next digit (7) from the dividend to 309 and continue with: 3097 / 550

Advancing to step 6:
If we divide 3097 by 550, we get 5 and a remainder of 347.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
Subtracting 2750 from 3097 leaves us with 347.
Take the next digit (6) from the dividend and append it to 347, then repeat: 3476 / 550

Moving on to step 7:
550 goes into 3476 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 12056.0
Subtract 3300 from 3476 to get 176.
Bring next digit (3) of the dividend behind the 176 and repeat the process: 1763 / 550

Advancing to step 8:
The number 550 fits into 1763 3 times, leaving a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 120563.0
Subtract 1650 from 1763 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 9:
When dividing 1130 by 550, we get 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 120563.2
Subtract 1100 from 1130 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
When dividing 300 by 550, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 120563.2
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
When dividing 3000 by 550, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 120563.205
If we take 2750 away from 3000, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
550 can be fit into 2500 4 times, resulting in a remainder of 300.
Put 4 as the next digit of the answer. 
Result so far: 120563.2054
If we take 2200 away from 2500, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
3000 divided by 550 is 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 120563.20545
Subtracting 2750 from 3000 leaves us with 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 14:
The number 550 fits into 2500 4 times, leaving a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 120563.205454
Subtracting 2200 from 2500 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
550 goes into 3000 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 120563.2054545
If we take 2750 away from 3000, we end up with 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 16:
550 can be fit into 2500 4 times, resulting in a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 120563.20545454
Subtract 2200 from 2500 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 120563.20545454, with a leftover of 3e-07.
