We're dividing 66871321 by 535 
We're looking to find how many times 535 goes into 66871321.

Let's proceed to step 1:
535 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 535

Going ahead to step 2:
66 divided by 535 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 535

Going ahead to step 3:
The number 535 fits into 668 1 times, leaving a remainder of 133.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 535 from 668 and we're left with 133.
Take the next digit (7) from the dividend and append it to 133, then repeat: 1337 / 535

Moving on to step 4:
If we divide 1337 by 535, we get 2 and a remainder of 267.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1070 from 1337 leaves us with 267.
Grab the next digit (1) from the dividend, add it to 267, then carry on: 2671 / 535

Going ahead to step 5:
When dividing 2671 by 535, we get 4 with a remainder of 531.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 2140 away from 2671, we end up with 531.
Grab the next digit (3) from the dividend, add it to 531, then carry on: 5313 / 535

Advancing to step 6:
535 can be fit into 5313 9 times, resulting in a remainder of 498.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
Subtract 4815 from 5313 to get 498.
Include the next digit (2) from the dividend after 498, then repeat: 4982 / 535

Moving on to step 7:
The number 535 fits into 4982 9 times, leaving a remainder of 167.
Put 9 as the next digit of the answer. 
Result so far: 12499.0
If we take 4815 away from 4982, we end up with 167.
Append the next digit (1) from the dividend to 167 and continue with: 1671 / 535

Let's proceed to step 8:
535 can be fit into 1671 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 124993.0
Subtracting 1605 from 1671 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
535 goes into 660 1 times with a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 124993.1
If we subtract 535 from 660, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 10:
535 goes into 1250 2 times with a remainder of 180.
The next digit of our result is 2. 
Result so far: 124993.12
Subtracting 1070 from 1250 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
If we divide 1800 by 535, we get 3 and a remainder of 195.
Put 3 as the next digit of the answer. 
Result so far: 124993.123
If we take 1605 away from 1800, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 12:
1950 divided by 535 is 3 with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 124993.1233
Deduct 1605 from 1950 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

In conclusion, the division gives 124993.1233 with a balance of 0.00345.
