4564952 divided by 621 
Let's see how many times 621 fits into 4564952.

Advancing to step 1:
If we divide 4 by 621, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 621

Step 2:
The number 621 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 621

Let's proceed to step 3:
When dividing 456 by 621, we get 0 with a remainder of 456.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 456 after subtracting 0 from 456.
Fetch the next digit (4) from the dividend, attach it to 456 and continue: 4564 / 621

Let's proceed to step 4:
621 can be fit into 4564 7 times, resulting in a remainder of 217.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4347 from 4564, we get 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 621

Step 5:
The number 621 fits into 2179 3 times, leaving a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 1863 from 2179 and we're left with 316.
Include the next digit (5) from the dividend after 316, then repeat: 3165 / 621

Step 6:
621 can be fit into 3165 5 times, resulting in a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 735.0
If we take 3105 away from 3165, we end up with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 621

Let's proceed to step 7:
The number 621 fits into 602 0 times, leaving a remainder of 602.
Write down 0 as next digit of the result. 
Result so far: 7350.0
Subtracting 0 from 602 leaves us with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 8:
621 goes into 6020 9 times with a remainder of 431.
Put 9 as the next digit of the answer. 
Result so far: 7350.9
Deduct 5589 from 6020 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 9:
If we divide 4310 by 621, we get 6 and a remainder of 584.
The next digit of our result is 6. 
Result so far: 7350.96
If we subtract 3726 from 4310, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Advancing to step 10:
5840 divided by 621 is 9 with a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 7350.969
If we take 5589 away from 5840, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 11:
2510 divided by 621 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7350.9694
If we take 2484 away from 2510, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
When dividing 260 by 621, we get 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 7350.9694
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
621 can be fit into 2600 4 times, resulting in a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 7350.969404
The remainder is 116 after subtracting 2484 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
621 can be fit into 1160 1 times, resulting in a remainder of 539.
Write down 1 as next digit of the result. 
Result so far: 7350.9694041
Subtracting 621 from 1160 leaves us with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Going ahead to step 15:
When dividing 5390 by 621, we get 8 with a remainder of 422.
Put 8 as the next digit of the answer. 
Result so far: 7350.96940418
The remainder is 422 after subtracting 4968 from 5390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

In conclusion, the division gives 7350.96940418 with a balance of 4.22e-07.
