We're dividing 821673 by 87 
Let's see how many times 87 fits into 821673.

Step 1:
8 divided by 87 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 87

Moving on to step 2:
82 divided by 87 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (1) from the dividend after 82, then repeat: 821 / 87

Advancing to step 3:
87 can be fit into 821 9 times, resulting in a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 783 away from 821, we end up with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 87

Moving on to step 4:
87 goes into 386 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 348 from 386 leaves us with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 87

On to step 5:
When dividing 387 by 87, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 944.0
Subtract 348 from 387 to get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 87

Let's proceed to step 6:
If we divide 393 by 87, we get 4 and a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 9444.0
The remainder is 45 after subtracting 348 from 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
450 divided by 87 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9444.5
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
If we divide 150 by 87, we get 1 and a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 9444.51
Deduct 87 from 150 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
630 divided by 87 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 9444.517
If we take 609 away from 630, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
210 divided by 87 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 9444.5172
If we subtract 174 from 210, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
87 can be fit into 360 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 9444.51724
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
If we divide 120 by 87, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 9444.517241
If we take 87 away from 120, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
87 goes into 330 3 times with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 9444.5172413
Deduct 261 from 330 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 14:
87 goes into 690 7 times with a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 9444.51724137
Deduct 609 from 690 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 9444.51724137 with a remaining 8.1e-08.
