We're dividing 73240790 by 609 
We want to figure out the number of times 73240790 can be divided by 609.

Let's proceed to step 1:
609 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 609

Advancing to step 2:
609 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 609

Moving on to step 3:
When dividing 732 by 609, we get 1 with a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 123 after subtracting 609 from 732.
Take the next digit (4) from the dividend and append it to 123, then repeat: 1234 / 609

Moving on to step 4:
The number 609 fits into 1234 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1218 from 1234 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 609

Let's proceed to step 5:
160 divided by 609 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 160, we end up with 160.
Include the next digit (7) from the dividend after 160, then repeat: 1607 / 609

Advancing to step 6:
If we divide 1607 by 609, we get 2 and a remainder of 389.
Write down 2 as next digit of the result. 
Result so far: 1202.0
If we take 1218 away from 1607, we end up with 389.
Take the next digit (9) from the dividend and append it to 389, then repeat: 3899 / 609

Going ahead to step 7:
3899 divided by 609 is 6 with a remainder of 245.
Write down 6 as next digit of the result. 
Result so far: 12026.0
The remainder is 245 after subtracting 3654 from 3899.
Append the next digit (0) from the dividend to 245 and continue with: 2450 / 609

Let's proceed to step 8:
2450 divided by 609 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 120264.0
If we take 2436 away from 2450, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
When dividing 140 by 609, we get 0 with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 120264.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
609 goes into 1400 2 times with a remainder of 182.
Put 2 as the next digit of the answer. 
Result so far: 120264.02
Deduct 1218 from 1400 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 11:
1820 divided by 609 is 2 with a remainder of 602.
Use 2 as the next digit of our solution. 
Result so far: 120264.022
Subtract 1218 from 1820 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

After the division, we end up with 120264.022 and a remainder of 0.0602.
