We look at the division of 23658040 by 621 
Our goal is to divide 23658040 by 621.

Let's proceed to step 1:
If we divide 2 by 621, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 621

Let's proceed to step 2:
23 divided by 621 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 621

Let's proceed to step 3:
621 can be fit into 236 0 times, resulting in a remainder of 236.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 236, we get 236.
Take the next digit (5) from the dividend and append it to 236, then repeat: 2365 / 621

Let's proceed to step 4:
621 can be fit into 2365 3 times, resulting in a remainder of 502.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1863 from 2365 and we're left with 502.
Fetch the next digit (8) from the dividend, attach it to 502 and continue: 5028 / 621

Moving on to step 5:
When dividing 5028 by 621, we get 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 4968 from 5028 and we're left with 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 621

Moving on to step 6:
The number 621 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 380.0
If we subtract 0 from 600, we get 600.
Fetch the next digit (4) from the dividend, attach it to 600 and continue: 6004 / 621

Advancing to step 7:
The number 621 fits into 6004 9 times, leaving a remainder of 415.
Write down 9 as next digit of the result. 
Result so far: 3809.0
Deduct 5589 from 6004 and we're left with 415.
Include the next digit (0) from the dividend after 415, then repeat: 4150 / 621

Moving on to step 8:
621 can be fit into 4150 6 times, resulting in a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 38096.0
Deduct 3726 from 4150 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 9:
621 can be fit into 4240 6 times, resulting in a remainder of 514.
The next digit of our result is 6. 
Result so far: 38096.6
Deduct 3726 from 4240 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 10:
621 can be fit into 5140 8 times, resulting in a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 38096.68
Subtracting 4968 from 5140 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 11:
The number 621 fits into 1720 2 times, leaving a remainder of 478.
The number 2 becomes the next digit in our result. 
Result so far: 38096.682
The remainder is 478 after subtracting 1242 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 12:
If we divide 4780 by 621, we get 7 and a remainder of 433.
The next digit of our result is 7. 
Result so far: 38096.6827
Subtract 4347 from 4780 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 13:
When dividing 4330 by 621, we get 6 with a remainder of 604.
The next digit of our result is 6. 
Result so far: 38096.68276
If we take 3726 away from 4330, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 14:
621 can be fit into 6040 9 times, resulting in a remainder of 451.
The next digit of our result is 9. 
Result so far: 38096.682769
Subtract 5589 from 6040 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 15:
If we divide 4510 by 621, we get 7 and a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 38096.6827697
If we subtract 4347 from 4510, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 16:
If we divide 1630 by 621, we get 2 and a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 38096.68276972
Subtracting 1242 from 1630 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 38096.68276972 with a remaining 3.88e-07.
