We look at the division of 73613214 by 840 
Our goal is to divide 73613214 by 840.

Let's proceed to step 1:
840 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 840

Step 2:
73 divided by 840 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 840

Moving on to step 3:
The number 840 fits into 736 0 times, leaving a remainder of 736.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 736 to get 736.
Take the next digit (1) from the dividend and append it to 736, then repeat: 7361 / 840

Step 4:
840 goes into 7361 8 times with a remainder of 641.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 6720 from 7361 to get 641.
Take the next digit (3) from the dividend and append it to 641, then repeat: 6413 / 840

Moving on to step 5:
The number 840 fits into 6413 7 times, leaving a remainder of 533.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 5880 from 6413 to get 533.
Include the next digit (2) from the dividend after 533, then repeat: 5332 / 840

Let's proceed to step 6:
The number 840 fits into 5332 6 times, leaving a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 876.0
If we take 5040 away from 5332, we end up with 292.
Fetch the next digit (1) from the dividend, attach it to 292 and continue: 2921 / 840

Let's proceed to step 7:
When dividing 2921 by 840, we get 3 with a remainder of 401.
Use 3 as the next digit of our solution. 
Result so far: 8763.0
If we take 2520 away from 2921, we end up with 401.
Bring next digit (4) of the dividend behind the 401 and repeat the process: 4014 / 840

Moving on to step 8:
If we divide 4014 by 840, we get 4 and a remainder of 654.
The number 4 becomes the next digit in our result. 
Result so far: 87634.0
Subtract 3360 from 4014 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 9:
6540 divided by 840 is 7 with a remainder of 660.
The number 7 becomes the next digit in our result. 
Result so far: 87634.7
Subtracting 5880 from 6540 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 10:
840 goes into 6600 7 times with a remainder of 720.
Use 7 as the next digit of our solution. 
Result so far: 87634.77
If we take 5880 away from 6600, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final result is 87634.77 with a remainder of 0.72.
