We're dividing 3651393 by 624 
Let's see how many times 624 fits into 3651393.

Going ahead to step 1:
The number 624 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 624

Going ahead to step 2:
624 can be fit into 36 0 times, resulting in a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 624

Moving on to step 3:
365 divided by 624 is 0 with a remainder of 365.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 365 to get 365.
Include the next digit (1) from the dividend after 365, then repeat: 3651 / 624

Advancing to step 4:
624 goes into 3651 5 times with a remainder of 531.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3120 away from 3651, we end up with 531.
Include the next digit (3) from the dividend after 531, then repeat: 5313 / 624

Advancing to step 5:
624 goes into 5313 8 times with a remainder of 321.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 4992 from 5313 to get 321.
Take the next digit (9) from the dividend and append it to 321, then repeat: 3219 / 624

Going ahead to step 6:
624 can be fit into 3219 5 times, resulting in a remainder of 99.
Write down 5 as next digit of the result. 
Result so far: 585.0
If we subtract 3120 from 3219, we get 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 624

On to step 7:
624 can be fit into 993 1 times, resulting in a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 5851.0
If we subtract 624 from 993, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 8:
624 goes into 3690 5 times with a remainder of 570.
Use 5 as the next digit of our solution. 
Result so far: 5851.5
The remainder is 570 after subtracting 3120 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 9:
624 can be fit into 5700 9 times, resulting in a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 5851.59
If we take 5616 away from 5700, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
When dividing 840 by 624, we get 1 with a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 5851.591
Deduct 624 from 840 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 11:
624 goes into 2160 3 times with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 5851.5913
Deduct 1872 from 2160 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 12:
The number 624 fits into 2880 4 times, leaving a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 5851.59134
Subtract 2496 from 2880 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 13:
If we divide 3840 by 624, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 5851.591346
If we subtract 3744 from 3840, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
960 divided by 624 is 1 with a remainder of 336.
Use 1 as the next digit of our solution. 
Result so far: 5851.5913461
Subtract 624 from 960 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 15:
If we divide 3360 by 624, we get 5 and a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 5851.59134615
The remainder is 240 after subtracting 3120 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 5851.59134615 with a remaining 2.4e-07.
