We look at the division of 85987309 by 429 
Let's see how many times 429 fits into 85987309.

Advancing to step 1:
When dividing 8 by 429, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 429

Let's proceed to step 2:
85 divided by 429 is 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 429

Step 3:
429 goes into 859 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 858 from 859 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 429

Step 4:
If we divide 18 by 429, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 429

On to step 5:
If we divide 187 by 429, we get 0 and a remainder of 187.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtracting 0 from 187 leaves us with 187.
Include the next digit (3) from the dividend after 187, then repeat: 1873 / 429

Advancing to step 6:
1873 divided by 429 is 4 with a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 2004.0
Subtract 1716 from 1873 to get 157.
Fetch the next digit (0) from the dividend, attach it to 157 and continue: 1570 / 429

On to step 7:
The number 429 fits into 1570 3 times, leaving a remainder of 283.
Use 3 as the next digit of our solution. 
Result so far: 20043.0
Deduct 1287 from 1570 and we're left with 283.
Grab the next digit (9) from the dividend, add it to 283, then carry on: 2839 / 429

On to step 8:
2839 divided by 429 is 6 with a remainder of 265.
Record the quotient 6 as the next digit in the result. 
Result so far: 200436.0
Subtracting 2574 from 2839 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
The number 429 fits into 2650 6 times, leaving a remainder of 76.
The next digit of our result is 6. 
Result so far: 200436.6
Subtracting 2574 from 2650 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 429 fits into 760 1 times, leaving a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 200436.61
The remainder is 331 after subtracting 429 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 11:
The number 429 fits into 3310 7 times, leaving a remainder of 307.
The number 7 becomes the next digit in our result. 
Result so far: 200436.617
If we take 3003 away from 3310, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 12:
The number 429 fits into 3070 7 times, leaving a remainder of 67.
The next digit of our result is 7. 
Result so far: 200436.6177
Deduct 3003 from 3070 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 200436.6177, and the remainder is 0.00067.
