879178 divided by 20 
We're looking to find how many times 20 goes into 879178.

Let's proceed to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 20

Advancing to step 2:
When dividing 87 by 20, we get 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 80 from 87 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 20

Let's proceed to step 3:
79 divided by 20 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 60 from 79 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 20

Going ahead to step 4:
20 can be fit into 191 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
If we take 180 away from 191, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 20

Going ahead to step 5:
When dividing 117 by 20, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 4395.0
Deduct 100 from 117 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 20

Moving on to step 6:
20 goes into 178 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 43958.0
If we take 160 away from 178, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 20 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 43958.9
If we subtract 180 from 180, we 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43958.9
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43958.9
Subtracting 0 from 0 leaves us 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 quotient of the division is 43958.9, and the remainder is 0.0.
