We're dividing 871940 by 84 
We want to figure out the number of times 871940 can be divided by 84.

Advancing to step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 84

Going ahead to step 2:
84 can be fit into 87 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 84 from 87 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 84

Moving on to step 3:
84 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 84

Moving on to step 4:
The number 84 fits into 319 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 67 after subtracting 252 from 319.
Bring next digit (4) of the dividend behind the 67 and repeat the process: 674 / 84

Advancing to step 5:
If we divide 674 by 84, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
Subtracting 672 from 674 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 84

On to step 6:
If we divide 20 by 84, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10380.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 84, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10380.2
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 84, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 10380.23
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
84 goes into 680 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10380.238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10380.238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 10380.23809
Subtracting 756 from 800 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 84 fits into 440 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 10380.238095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
84 goes into 200 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 10380.2380952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 10380.23809523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 10380.23809523 and a remainder of 6.8e-08.
