66515947 divided by 742 
We want to figure out the number of times 66515947 can be divided by 742.

Going ahead to step 1:
742 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
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 742

Advancing to step 2:
742 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 742

Step 3:
If we divide 665 by 742, we get 0 and a remainder of 665.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 665 and we're left with 665.
Take the next digit (1) from the dividend and append it to 665, then repeat: 6651 / 742

Advancing to step 4:
6651 divided by 742 is 8 with a remainder of 715.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 5936 away from 6651, we end up with 715.
Append the next digit (5) from the dividend to 715 and continue with: 7155 / 742

On to step 5:
If we divide 7155 by 742, we get 9 and a remainder of 477.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 6678 from 7155 and we're left with 477.
Include the next digit (9) from the dividend after 477, then repeat: 4779 / 742

Moving on to step 6:
742 goes into 4779 6 times with a remainder of 327.
Record the quotient 6 as the next digit in the result. 
Result so far: 896.0
Subtracting 4452 from 4779 leaves us with 327.
Append the next digit (4) from the dividend to 327 and continue with: 3274 / 742

Moving on to step 7:
742 can be fit into 3274 4 times, resulting in a remainder of 306.
Use 4 as the next digit of our solution. 
Result so far: 8964.0
The remainder is 306 after subtracting 2968 from 3274.
Append the next digit (7) from the dividend to 306 and continue with: 3067 / 742

On to step 8:
If we divide 3067 by 742, we get 4 and a remainder of 99.
The number 4 becomes the next digit in our result. 
Result so far: 89644.0
Subtracting 2968 from 3067 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
990 divided by 742 is 1 with a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 89644.1
If we take 742 away from 990, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
2480 divided by 742 is 3 with a remainder of 254.
Use 3 as the next digit of our solution. 
Result so far: 89644.13
If we take 2226 away from 2480, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 11:
The number 742 fits into 2540 3 times, leaving a remainder of 314.
The next digit of our result is 3. 
Result so far: 89644.133
If we take 2226 away from 2540, we end up with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final outcome is 89644.133, with a leftover of 0.0314.
