Let's divide 55340223 by 621
Our goal is to divide 55340223 by 621.

Let's proceed to step 1:
If we divide 5 by 621, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 621

Advancing to step 2:
The number 621 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 621

On to step 3:
When dividing 553 by 621, we get 0 with a remainder of 553.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 553, we end up with 553.
Bring next digit (4) of the dividend behind the 553 and repeat the process: 5534 / 621

Going ahead to step 4:
621 goes into 5534 8 times with a remainder of 566.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 4968 from 5534 to get 566.
Append the next digit (0) from the dividend to 566 and continue with: 5660 / 621

Going ahead to step 5:
The number 621 fits into 5660 9 times, leaving a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we take 5589 away from 5660, we end up with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 621

Step 6:
712 divided by 621 is 1 with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 891.0
The remainder is 91 after subtracting 621 from 712.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 621

Going ahead to step 7:
When dividing 912 by 621, we get 1 with a remainder of 291.
The next digit of our result is 1. 
Result so far: 8911.0
Deduct 621 from 912 and we're left with 291.
Take the next digit (3) from the dividend and append it to 291, then repeat: 2913 / 621

Step 8:
The number 621 fits into 2913 4 times, leaving a remainder of 429.
Use 4 as the next digit of our solution. 
Result so far: 89114.0
If we take 2484 away from 2913, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
4290 divided by 621 is 6 with a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 89114.6
If we subtract 3726 from 4290, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 10:
621 can be fit into 5640 9 times, resulting in a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 89114.69
If we subtract 5589 from 5640, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 11:
621 goes into 510 0 times with a remainder of 510.
The next digit of our result is 0. 
Result so far: 89114.69
Subtracting 0 from 510 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 12:
When dividing 5100 by 621, we get 8 with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 89114.6908
The remainder is 132 after subtracting 4968 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
If we divide 1320 by 621, we get 2 and a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 89114.69082
The remainder is 78 after subtracting 1242 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
When dividing 780 by 621, we get 1 with a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 89114.690821
Subtract 621 from 780 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 15:
When dividing 1590 by 621, we get 2 with a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 89114.6908212
If we subtract 1242 from 1590, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 16:
When dividing 3480 by 621, we get 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 89114.69082125
Subtract 3105 from 3480 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final outcome is 89114.69082125, with a leftover of 3.75e-07.
