Let's divide 45600521 by 443
We want to divide 45600521 by 443.

Step 1:
The number 443 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 443

Moving on to step 2:
The number 443 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 443

Advancing to step 3:
456 divided by 443 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 443 from 456 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 443

Moving on to step 4:
If we divide 130 by 443, we get 0 and a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 130 after subtracting 0 from 130.
Take the next digit (0) from the dividend and append it to 130, then repeat: 1300 / 443

Let's proceed to step 5:
If we divide 1300 by 443, we get 2 and a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 886 from 1300 to get 414.
Append the next digit (5) from the dividend to 414 and continue with: 4145 / 443

Going ahead to step 6:
4145 divided by 443 is 9 with a remainder of 158.
The next digit of our result is 9. 
Result so far: 1029.0
If we subtract 3987 from 4145, we get 158.
Bring next digit (2) of the dividend behind the 158 and repeat the process: 1582 / 443

Advancing to step 7:
When dividing 1582 by 443, we get 3 with a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 10293.0
If we take 1329 away from 1582, we end up with 253.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 443

Moving on to step 8:
443 can be fit into 2531 5 times, resulting in a remainder of 316.
Put 5 as the next digit of the answer. 
Result so far: 102935.0
Subtract 2215 from 2531 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 9:
The number 443 fits into 3160 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 102935.7
Deduct 3101 from 3160 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
590 divided by 443 is 1 with a remainder of 147.
The next digit of our result is 1. 
Result so far: 102935.71
The remainder is 147 after subtracting 443 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 11:
443 can be fit into 1470 3 times, resulting in a remainder of 141.
The next digit of our result is 3. 
Result so far: 102935.713
Deduct 1329 from 1470 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 12:
When dividing 1410 by 443, we get 3 with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 102935.7133
If we subtract 1329 from 1410, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

After the division, we end up with 102935.7133 and a remainder of 0.00081.
