Let's divide 42179973 by 875
Our goal is to divide 42179973 by 875.

Step 1:
If we divide 4 by 875, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 875

Moving on to step 2:
When dividing 42 by 875, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 875

Going ahead to step 3:
875 goes into 421 0 times with a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 421, we end up with 421.
Fetch the next digit (7) from the dividend, attach it to 421 and continue: 4217 / 875

On to step 4:
When dividing 4217 by 875, we get 4 with a remainder of 717.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3500 from 4217, we get 717.
Fetch the next digit (9) from the dividend, attach it to 717 and continue: 7179 / 875

Let's proceed to step 5:
7179 divided by 875 is 8 with a remainder of 179.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 7000 from 7179 leaves us with 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 875

Moving on to step 6:
875 goes into 1799 2 times with a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 482.0
If we take 1750 away from 1799, we end up with 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 875

Moving on to step 7:
When dividing 497 by 875, we get 0 with a remainder of 497.
The next digit of our result is 0. 
Result so far: 4820.0
The remainder is 497 after subtracting 0 from 497.
Bring next digit (3) of the dividend behind the 497 and repeat the process: 4973 / 875

Moving on to step 8:
875 can be fit into 4973 5 times, resulting in a remainder of 598.
The number 5 becomes the next digit in our result. 
Result so far: 48205.0
Subtract 4375 from 4973 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 9:
The number 875 fits into 5980 6 times, leaving a remainder of 730.
Write down 6 as next digit of the result. 
Result so far: 48205.6
Deduct 5250 from 5980 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 10:
875 can be fit into 7300 8 times, resulting in a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 48205.68
If we subtract 7000 from 7300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
3000 divided by 875 is 3 with a remainder of 375.
The number 3 becomes the next digit in our result. 
Result so far: 48205.683
The remainder is 375 after subtracting 2625 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 12:
If we divide 3750 by 875, we get 4 and a remainder of 250.
Record the quotient 4 as the next digit in the result. 
Result so far: 48205.6834
If we subtract 3500 from 3750, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
875 goes into 2500 2 times with a remainder of 750.
Put 2 as the next digit of the answer. 
Result so far: 48205.68342
If we take 1750 away from 2500, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 14:
The number 875 fits into 7500 8 times, leaving a remainder of 500.
Use 8 as the next digit of our solution. 
Result so far: 48205.683428
Deduct 7000 from 7500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 15:
875 can be fit into 5000 5 times, resulting in a remainder of 625.
The next digit of our result is 5. 
Result so far: 48205.6834285
Subtract 4375 from 5000 to get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 16:
When dividing 6250 by 875, we get 7 with a remainder of 125.
Use 7 as the next digit of our solution. 
Result so far: 48205.68342857
The remainder is 125 after subtracting 6125 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 48205.68342857, and the remainder is 1.25e-07.
