We're dividing 66860030 by 735 
Our goal is to divide 66860030 by 735.

Step 1:
The number 735 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
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 735

Moving on to step 2:
735 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
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 / 735

Advancing to step 3:
735 goes into 668 0 times with a remainder of 668.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 668 leaves us with 668.
Append the next digit (6) from the dividend to 668 and continue with: 6686 / 735

Going ahead to step 4:
735 goes into 6686 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 9.0
If we take 6615 away from 6686, we end up with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 735

On to step 5:
735 goes into 710 0 times with a remainder of 710.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 710 and we're left with 710.
Append the next digit (0) from the dividend to 710 and continue with: 7100 / 735

Going ahead to step 6:
The number 735 fits into 7100 9 times, leaving a remainder of 485.
Use 9 as the next digit of our solution. 
Result so far: 909.0
If we subtract 6615 from 7100, we get 485.
Append the next digit (3) from the dividend to 485 and continue with: 4853 / 735

Going ahead to step 7:
735 can be fit into 4853 6 times, resulting in a remainder of 443.
Put 6 as the next digit of the answer. 
Result so far: 9096.0
If we take 4410 away from 4853, we end up with 443.
Append the next digit (0) from the dividend to 443 and continue with: 4430 / 735

Going ahead to step 8:
735 goes into 4430 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 90966.0
Deduct 4410 from 4430 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
735 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 90966.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
735 goes into 2000 2 times with a remainder of 530.
The next digit of our result is 2. 
Result so far: 90966.02
If we take 1470 away from 2000, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 11:
735 can be fit into 5300 7 times, resulting in a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 90966.027
If we subtract 5145 from 5300, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 12:
735 can be fit into 1550 2 times, resulting in a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 90966.0272
If we subtract 1470 from 1550, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 735, we get 1 and a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 90966.02721
The remainder is 65 after subtracting 735 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
The number 735 fits into 650 0 times, leaving a remainder of 650.
Write down 0 as next digit of the result. 
Result so far: 90966.02721
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 15:
When dividing 6500 by 735, we get 8 with a remainder of 620.
The next digit of our result is 8. 
Result so far: 90966.0272108
If we take 5880 away from 6500, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 16:
6200 divided by 735 is 8 with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 90966.02721088
Deduct 5880 from 6200 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 90966.02721088 with a remainder of 3.2e-07.
