We're dividing 66869934 by 754 
We want to figure out the number of times 66869934 can be divided by 754.

Step 1:
754 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 754

Moving on to step 2:
66 divided by 754 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 754

Step 3:
754 goes into 668 0 times with a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 668 and we're left with 668.
Take the next digit (6) from the dividend and append it to 668, then repeat: 6686 / 754

On to step 4:
When dividing 6686 by 754, we get 8 with a remainder of 654.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 654 after subtracting 6032 from 6686.
Grab the next digit (9) from the dividend, add it to 654, then carry on: 6549 / 754

Advancing to step 5:
754 can be fit into 6549 8 times, resulting in a remainder of 517.
The next digit of our result is 8. 
Result so far: 88.0
If we subtract 6032 from 6549, we get 517.
Include the next digit (9) from the dividend after 517, then repeat: 5179 / 754

Advancing to step 6:
754 can be fit into 5179 6 times, resulting in a remainder of 655.
Write down 6 as next digit of the result. 
Result so far: 886.0
If we subtract 4524 from 5179, we get 655.
Include the next digit (3) from the dividend after 655, then repeat: 6553 / 754

On to step 7:
When dividing 6553 by 754, we get 8 with a remainder of 521.
The number 8 becomes the next digit in our result. 
Result so far: 8868.0
Subtract 6032 from 6553 to get 521.
Include the next digit (4) from the dividend after 521, then repeat: 5214 / 754

On to step 8:
754 can be fit into 5214 6 times, resulting in a remainder of 690.
The next digit of our result is 6. 
Result so far: 88686.0
Subtract 4524 from 5214 to get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 9:
When dividing 6900 by 754, we get 9 with a remainder of 114.
Write down 9 as next digit of the result. 
Result so far: 88686.9
If we subtract 6786 from 6900, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
The number 754 fits into 1140 1 times, leaving a remainder of 386.
Put 1 as the next digit of the answer. 
Result so far: 88686.91
If we take 754 away from 1140, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Advancing to step 11:
If we divide 3860 by 754, we get 5 and a remainder of 90.
The next digit of our result is 5. 
Result so far: 88686.915
The remainder is 90 after subtracting 3770 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
If we divide 900 by 754, we get 1 and a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 88686.9151
Subtracting 754 from 900 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 13:
754 can be fit into 1460 1 times, resulting in a remainder of 706.
Write down 1 as next digit of the result. 
Result so far: 88686.91511
If we take 754 away from 1460, we end up with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

After the division, we end up with 88686.91511 and a remainder of 0.000706.
