870375 divided by 4 
We're looking to find how many times 4 goes into 870375.

Advancing to step 1:
4 goes into 8 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 8 away from 8, we end up with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 4

On to step 2:
When dividing 7 by 4, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 4 away from 7, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Advancing to step 3:
4 goes into 30 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 28 from 30 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 4

On to step 4:
The number 4 fits into 23 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 2175.0
Deduct 20 from 23 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 4

Step 5:
When dividing 37 by 4, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 21759.0
The remainder is 1 after subtracting 36 from 37.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Step 6:
If we divide 15 by 4, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 217593.0
The remainder is 3 after subtracting 12 from 15.
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:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 217593.7
If we subtract 28 from 30, 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.

Step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 217593.75
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:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 217593.75
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 217593.75
Subtract 0 from 0 to get 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 outcome is 217593.75, with a leftover of 0.0.
