We look at the division of 873622 by 84 
We want to figure out the number of times 873622 can be divided by 84.

Step 1:
84 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 84

Going ahead to step 2:
The number 84 fits into 87 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 84 away from 87, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 84

Let's proceed to step 3:
The number 84 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 33, we end up with 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 84

On to step 4:
If we divide 336 by 84, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we subtract 336 from 336, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 84

Step 5:
84 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 84

Going ahead to step 6:
The number 84 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 10400.0
If we take 0 away from 22, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 84, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 10400.2
If we subtract 168 from 220, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 10400.26
If we take 504 away from 520, 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.

Advancing to step 9:
If we divide 160 by 84, we get 1 and a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 10400.261
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
84 goes into 760 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 10400.2619
Subtracting 756 from 760 leaves us 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.

Step 11:
84 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10400.2619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 10400.261904
The remainder is 64 after subtracting 336 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
84 goes into 640 7 times with a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 10400.2619047
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 10400.26190476
Deduct 504 from 520 and we're left 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.

The final outcome is 10400.26190476, with a leftover of 1.6e-08.
