We're dividing 86853031 by 473 
Let's see how many times 473 fits into 86853031.

On to step 1:
If we divide 8 by 473, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 473

Going ahead to step 2:
If we divide 86 by 473, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 473

Let's proceed to step 3:
The number 473 fits into 868 1 times, leaving a remainder of 395.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 473 from 868 to get 395.
Fetch the next digit (5) from the dividend, attach it to 395 and continue: 3955 / 473

Advancing to step 4:
If we divide 3955 by 473, we get 8 and a remainder of 171.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 3784 from 3955, we get 171.
Grab the next digit (3) from the dividend, add it to 171, then carry on: 1713 / 473

Moving on to step 5:
When dividing 1713 by 473, we get 3 with a remainder of 294.
The next digit of our result is 3. 
Result so far: 183.0
If we take 1419 away from 1713, we end up with 294.
Fetch the next digit (0) from the dividend, attach it to 294 and continue: 2940 / 473

Going ahead to step 6:
If we divide 2940 by 473, we get 6 and a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 1836.0
If we subtract 2838 from 2940, we get 102.
Take the next digit (3) from the dividend and append it to 102, then repeat: 1023 / 473

Step 7:
When dividing 1023 by 473, we get 2 with a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 18362.0
The remainder is 77 after subtracting 946 from 1023.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 473

On to step 8:
473 can be fit into 771 1 times, resulting in a remainder of 298.
The number 1 becomes the next digit in our result. 
Result so far: 183621.0
Subtract 473 from 771 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
The number 473 fits into 2980 6 times, leaving a remainder of 142.
Record the quotient 6 as the next digit in the result. 
Result so far: 183621.6
Subtract 2838 from 2980 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 10:
1420 divided by 473 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 183621.63
If we subtract 1419 from 1420, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
10 divided by 473 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 183621.63
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
473 goes into 100 0 times with a remainder of 100.
The next digit of our result is 0. 
Result so far: 183621.63
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 183621.63, and the remainder is 0.001.
