877169 divided by 20 
We want to figure out the number of times 877169 can be divided by 20.

Going ahead to step 1:
20 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Advancing to step 2:
20 can be fit into 87 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 7 after subtracting 80 from 87.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 20

Step 3:
20 goes into 77 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 60 from 77 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Moving on to step 4:
20 goes into 171 8 times with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
The remainder is 11 after subtracting 160 from 171.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 20

Let's proceed to step 5:
116 divided by 20 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 4385.0
Subtract 100 from 116 to get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 20

Step 6:
The number 20 fits into 169 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 43858.0
The remainder is 9 after subtracting 160 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 20 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 43858.4
If we subtract 80 from 90, 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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 43858.45
If we take 100 away from 100, 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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43858.45
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43858.45
If we subtract 0 from 0, 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.

Our division results in 43858.45 with a remaining 0.0.
