We divide 3191299 by 621
We want to divide 3191299 by 621.

Advancing to step 1:
The number 621 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.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 621

Moving on to step 2:
621 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 621

Advancing to step 3:
If we divide 319 by 621, we get 0 and a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 319 after subtracting 0 from 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 621

Going ahead to step 4:
If we divide 3191 by 621, we get 5 and a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 3105 from 3191 to get 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 621

Advancing to step 5:
If we divide 862 by 621, we get 1 and a remainder of 241.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 621 from 862 leaves us with 241.
Take the next digit (9) from the dividend and append it to 241, then repeat: 2419 / 621

Going ahead to step 6:
If we divide 2419 by 621, we get 3 and a remainder of 556.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we take 1863 away from 2419, we end up with 556.
Append the next digit (9) from the dividend to 556 and continue with: 5569 / 621

Moving on to step 7:
621 can be fit into 5569 8 times, resulting in a remainder of 601.
The next digit of our result is 8. 
Result so far: 5138.0
Subtracting 4968 from 5569 leaves us with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Let's proceed to step 8:
The number 621 fits into 6010 9 times, leaving a remainder of 421.
Write down 9 as next digit of the result. 
Result so far: 5138.9
If we subtract 5589 from 6010, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Moving on to step 9:
4210 divided by 621 is 6 with a remainder of 484.
The next digit of our result is 6. 
Result so far: 5138.96
The remainder is 484 after subtracting 3726 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 10:
621 goes into 4840 7 times with a remainder of 493.
The number 7 becomes the next digit in our result. 
Result so far: 5138.967
Deduct 4347 from 4840 and we're left with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Let's proceed to step 11:
The number 621 fits into 4930 7 times, leaving a remainder of 583.
The next digit of our result is 7. 
Result so far: 5138.9677
Deduct 4347 from 4930 and we're left with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

In conclusion, the division gives 5138.9677 with a balance of 0.00583.
