868438 ÷ 71 
We want to divide 868438 by 71.

Step 1:
8 divided by 71 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 71

On to step 2:
86 divided by 71 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 71 from 86 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 71

Advancing to step 3:
When dividing 158 by 71, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 142 from 158 and we're left with 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 71

Moving on to step 4:
164 divided by 71 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 122.0
If we take 142 away from 164, we end up with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 71

Let's proceed to step 5:
71 can be fit into 223 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1223.0
The remainder is 10 after subtracting 213 from 223.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 71

On to step 6:
When dividing 108 by 71, we get 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 12231.0
Subtracting 71 from 108 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 71, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12231.5
The remainder is 15 after subtracting 355 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
The number 71 fits into 150 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 12231.52
The remainder is 8 after subtracting 142 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 71, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 12231.521
If we take 71 away from 80, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
71 can be fit into 90 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 12231.5211
If we subtract 71 from 90, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 12231.5211, and the remainder is 0.00019.
