We look at the division of 3620123 by 724 
We're looking to find how many times 724 goes into 3620123.

Step 1:
The number 724 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 724

Step 2:
If we divide 36 by 724, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 724

Moving on to step 3:
724 goes into 362 0 times with a remainder of 362.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 362 and we're left with 362.
Take the next digit (0) from the dividend and append it to 362, then repeat: 3620 / 724

On to step 4:
724 can be fit into 3620 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3620 away from 3620, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 724

On to step 5:
If we divide 1 by 724, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 724

On to step 6:
724 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 500.0
Subtract 0 from 12 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 724

On to step 7:
724 goes into 123 0 times with a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 5000.0
Deduct 0 from 123 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 8:
1230 divided by 724 is 1 with a remainder of 506.
Use 1 as the next digit of our solution. 
Result so far: 5000.1
If we subtract 724 from 1230, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 9:
If we divide 5060 by 724, we get 6 and a remainder of 716.
The number 6 becomes the next digit in our result. 
Result so far: 5000.16
Deduct 4344 from 5060 and we're left with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Going ahead to step 10:
The number 724 fits into 7160 9 times, leaving a remainder of 644.
Record the quotient 9 as the next digit in the result. 
Result so far: 5000.169
Deduct 6516 from 7160 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 11:
When dividing 6440 by 724, we get 8 with a remainder of 648.
Use 8 as the next digit of our solution. 
Result so far: 5000.1698
If we subtract 5792 from 6440, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 12:
724 goes into 6480 8 times with a remainder of 688.
The next digit of our result is 8. 
Result so far: 5000.16988
Deduct 5792 from 6480 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

The final outcome is 5000.16988, with a leftover of 0.000688.
