We divide 143434 by 86
Our goal is to divide 143434 by 86.

Moving on to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 86

Advancing to step 2:
86 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 86

Let's proceed to step 3:
86 can be fit into 143 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 86 from 143 and we're left with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 86

Step 4:
86 goes into 574 6 times with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 516 from 574 to get 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 86

On to step 5:
86 goes into 583 6 times with a remainder of 67.
Write down 6 as next digit of the result. 
Result so far: 166.0
Subtracting 516 from 583 leaves us with 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 86

Advancing to step 6:
If we divide 674 by 86, we get 7 and a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 1667.0
If we subtract 602 from 674, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
86 goes into 720 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1667.8
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
86 goes into 320 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 1667.83
If we take 258 away from 320, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
86 can be fit into 620 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1667.837
Subtract 602 from 620 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
When dividing 180 by 86, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1667.8372
If we take 172 away from 180, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 1667.8372
If we subtract 0 from 80, 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.

Going ahead to step 12:
The number 86 fits into 800 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 1667.837209
The remainder is 26 after subtracting 774 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
When dividing 260 by 86, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1667.8372093
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
The number 86 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1667.8372093
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1667.8372093 and a remainder of 2e-08.
