We divide 877810 by 42
Our goal is to divide 877810 by 42.

Moving on to step 1:
42 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 42

Advancing to step 2:
42 goes into 87 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 84 from 87 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 42

Advancing to step 3:
42 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 42

Advancing to step 4:
When dividing 378 by 42, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
If we subtract 378 from 378, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 42

Going ahead to step 5:
1 divided by 42 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 2090.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 42

Going ahead to step 6:
If we divide 10 by 42, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20900.0
If we take 0 away from 10, we end up with 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 7:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 20900.2
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
160 divided by 42 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 20900.23
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 20900.238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 20900.238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 42, we get 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 20900.23809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 20900.238095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 42 fits into 100 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 20900.2380952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 20900.23809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 20900.23809523, with a leftover of 3.4e-08.
