143625 ÷ 86 
Our goal is to divide 143625 by 86.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 86

Going ahead to step 2:
14 divided by 86 is 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 86

Step 3:
143 divided by 86 is 1 with a remainder of 57.
The next digit of our result is 1. 
Result so far: 1.0
If we take 86 away from 143, we end up with 57.
Include the next digit (6) from the dividend after 57, then repeat: 576 / 86

Going ahead to step 4:
86 goes into 576 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 60 after subtracting 516 from 576.
Grab the next digit (2) from the dividend, add it to 60, then carry on: 602 / 86

Going ahead to step 5:
The number 86 fits into 602 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 602 from 602, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 86

Let's proceed to step 6:
86 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1670.0
Subtracting 0 from 5 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 86, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1670.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 1670.05
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
If we divide 700 by 86, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1670.058
Subtracting 688 from 700 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1670.0581
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
86 goes into 340 3 times with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 1670.05813
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 12:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1670.058139
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
If we divide 460 by 86, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 1670.0581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1670.05813953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 1670.05813953 and a remainder of 4.2e-08.
