We look at the division of 73445530 by 840 
Let's see how many times 840 fits into 73445530.

On to step 1:
840 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 840

Going ahead to step 2:
840 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 840

On to step 3:
If we divide 734 by 840, we get 0 and a remainder of 734.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 734 to get 734.
Take the next digit (4) from the dividend and append it to 734, then repeat: 7344 / 840

Going ahead to step 4:
840 goes into 7344 8 times with a remainder of 624.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6720 from 7344, we get 624.
Take the next digit (5) from the dividend and append it to 624, then repeat: 6245 / 840

On to step 5:
6245 divided by 840 is 7 with a remainder of 365.
The next digit of our result is 7. 
Result so far: 87.0
Deduct 5880 from 6245 and we're left with 365.
Append the next digit (5) from the dividend to 365 and continue with: 3655 / 840

Let's proceed to step 6:
3655 divided by 840 is 4 with a remainder of 295.
The number 4 becomes the next digit in our result. 
Result so far: 874.0
If we subtract 3360 from 3655, we get 295.
Include the next digit (3) from the dividend after 295, then repeat: 2953 / 840

Going ahead to step 7:
2953 divided by 840 is 3 with a remainder of 433.
Write down 3 as next digit of the result. 
Result so far: 8743.0
If we subtract 2520 from 2953, we get 433.
Bring next digit (0) of the dividend behind the 433 and repeat the process: 4330 / 840

Advancing to step 8:
When dividing 4330 by 840, we get 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 87435.0
If we take 4200 away from 4330, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
The number 840 fits into 1300 1 times, leaving a remainder of 460.
Write down 1 as next digit of the result. 
Result so far: 87435.1
Subtract 840 from 1300 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
840 goes into 4600 5 times with a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 87435.15
If we subtract 4200 from 4600, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
If we divide 4000 by 840, we get 4 and a remainder of 640.
Record the quotient 4 as the next digit in the result. 
Result so far: 87435.154
If we take 3360 away from 4000, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 12:
The number 840 fits into 6400 7 times, leaving a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 87435.1547
Subtract 5880 from 6400 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 13:
If we divide 5200 by 840, we get 6 and a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 87435.15476
If we subtract 5040 from 5200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
The number 840 fits into 1600 1 times, leaving a remainder of 760.
The next digit of our result is 1. 
Result so far: 87435.154761
The remainder is 760 after subtracting 840 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 15:
The number 840 fits into 7600 9 times, leaving a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 87435.1547619
If we subtract 7560 from 7600, we 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.

Step 16:
840 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 87435.1547619
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 87435.1547619 with a remainder of 4e-07.
