18520451 ÷ 628 
Our goal is to divide 18520451 by 628.

Step 1:
The number 628 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 628

Let's proceed to step 2:
628 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 628

Step 3:
When dividing 185 by 628, we get 0 with a remainder of 185.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 185, we end up with 185.
Fetch the next digit (2) from the dividend, attach it to 185 and continue: 1852 / 628

Going ahead to step 4:
1852 divided by 628 is 2 with a remainder of 596.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1256 from 1852 and we're left with 596.
Grab the next digit (0) from the dividend, add it to 596, then carry on: 5960 / 628

Let's proceed to step 5:
If we divide 5960 by 628, we get 9 and a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 5652 away from 5960, we end up with 308.
Grab the next digit (4) from the dividend, add it to 308, then carry on: 3084 / 628

On to step 6:
3084 divided by 628 is 4 with a remainder of 572.
Write down 4 as next digit of the result. 
Result so far: 294.0
If we take 2512 away from 3084, we end up with 572.
Append the next digit (5) from the dividend to 572 and continue with: 5725 / 628

Advancing to step 7:
628 goes into 5725 9 times with a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 2949.0
If we subtract 5652 from 5725, we get 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 628

Moving on to step 8:
731 divided by 628 is 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 29491.0
Subtracting 628 from 731 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 9:
1030 divided by 628 is 1 with a remainder of 402.
Record the quotient 1 as the next digit in the result. 
Result so far: 29491.1
Subtract 628 from 1030 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 10:
4020 divided by 628 is 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 29491.16
Subtracting 3768 from 4020 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 11:
If we divide 2520 by 628, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 29491.164
Deduct 2512 from 2520 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 628 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 29491.164
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
800 divided by 628 is 1 with a remainder of 172.
Record the quotient 1 as the next digit in the result. 
Result so far: 29491.16401
If we subtract 628 from 800, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 14:
When dividing 1720 by 628, we get 2 with a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 29491.164012
If we subtract 1256 from 1720, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 15:
628 goes into 4640 7 times with a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 29491.1640127
If we subtract 4396 from 4640, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 16:
If we divide 2440 by 628, we get 3 and a remainder of 556.
Record the quotient 3 as the next digit in the result. 
Result so far: 29491.16401273
The remainder is 556 after subtracting 1884 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

In conclusion, the division gives 29491.16401273 with a balance of 5.56e-07.
