We're dividing 672571 by 4 
We want to divide 672571 by 4.

Step 1:
4 goes into 6 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 4

Moving on to step 2:
4 goes into 27 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 24 from 27 to get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Moving on to step 3:
If we divide 32 by 4, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
If we take 32 away from 32, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

Step 4:
5 divided by 4 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1681.0
The remainder is 1 after subtracting 4 from 5.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 4

Step 5:
When dividing 17 by 4, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 16814.0
If we take 16 away from 17, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 4

Advancing to step 6:
The number 4 fits into 11 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 168142.0
The remainder is 3 after subtracting 8 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
4 goes into 30 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 168142.7
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 4, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 168142.75
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 168142.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 168142.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 168142.75 with a remainder of 0.0.
