66710700 ÷ 17 
Our goal is to divide 66710700 by 17.

Advancing to step 1:
The number 17 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the 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 / 17

Moving on to step 2:
The number 17 fits into 66 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 51 from 66 leaves us with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 17

Let's proceed to step 3:
157 divided by 17 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we subtract 153 from 157, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 17

Moving on to step 4:
When dividing 41 by 17, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 392.0
Deduct 34 from 41 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 17

Let's proceed to step 5:
70 divided by 17 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 3924.0
If we take 68 away from 70, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 17

On to step 6:
17 can be fit into 27 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 39241.0
Deduct 17 from 27 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 17

On to step 7:
100 divided by 17 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 392415.0
If we take 85 away from 100, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 17

On to step 8:
150 divided by 17 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 3924158.0
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 3924158.8
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 17, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 3924158.82
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
If we divide 60 by 17, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3924158.823
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
The number 17 fits into 90 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3924158.8235
Deduct 85 from 90 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
17 goes into 50 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 3924158.82352
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 17, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 3924158.823529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
When dividing 70 by 17, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3924158.8235294
If we take 68 away from 70, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 16:
If we divide 20 by 17, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3924158.82352941
Deduct 17 from 20 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 3924158.82352941 and a remainder of 3e-09.
