45422189 ÷ 654 
We want to divide 45422189 by 654.

On to step 1:
If we divide 4 by 654, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 654

Advancing to step 2:
654 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 654

Going ahead to step 3:
654 can be fit into 454 0 times, resulting in a remainder of 454.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 454 leaves us with 454.
Take the next digit (2) from the dividend and append it to 454, then repeat: 4542 / 654

On to step 4:
4542 divided by 654 is 6 with a remainder of 618.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3924 from 4542 leaves us with 618.
Fetch the next digit (2) from the dividend, attach it to 618 and continue: 6182 / 654

Going ahead to step 5:
654 can be fit into 6182 9 times, resulting in a remainder of 296.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 296 after subtracting 5886 from 6182.
Fetch the next digit (1) from the dividend, attach it to 296 and continue: 2961 / 654

Going ahead to step 6:
2961 divided by 654 is 4 with a remainder of 345.
The next digit of our result is 4. 
Result so far: 694.0
Subtract 2616 from 2961 to get 345.
Append the next digit (8) from the dividend to 345 and continue with: 3458 / 654

Advancing to step 7:
The number 654 fits into 3458 5 times, leaving a remainder of 188.
Put 5 as the next digit of the answer. 
Result so far: 6945.0
The remainder is 188 after subtracting 3270 from 3458.
Bring next digit (9) of the dividend behind the 188 and repeat the process: 1889 / 654

Moving on to step 8:
654 can be fit into 1889 2 times, resulting in a remainder of 581.
Put 2 as the next digit of the answer. 
Result so far: 69452.0
If we subtract 1308 from 1889, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Let's proceed to step 9:
If we divide 5810 by 654, we get 8 and a remainder of 578.
The next digit of our result is 8. 
Result so far: 69452.8
Subtracting 5232 from 5810 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 10:
654 can be fit into 5780 8 times, resulting in a remainder of 548.
The next digit of our result is 8. 
Result so far: 69452.88
Subtract 5232 from 5780 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Our division results in 69452.88 with a remaining 0.548.
