We look at the division of 99746451 by 510 
Our goal is to divide 99746451 by 510.

Step 1:
510 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 510

Step 2:
When dividing 99 by 510, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 510

Going ahead to step 3:
510 can be fit into 997 1 times, resulting in a remainder of 487.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 510 from 997 and we're left with 487.
Include the next digit (4) from the dividend after 487, then repeat: 4874 / 510

On to step 4:
4874 divided by 510 is 9 with a remainder of 284.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 4590 from 4874 to get 284.
Fetch the next digit (6) from the dividend, attach it to 284 and continue: 2846 / 510

Going ahead to step 5:
510 goes into 2846 5 times with a remainder of 296.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 2550 from 2846 and we're left with 296.
Take the next digit (4) from the dividend and append it to 296, then repeat: 2964 / 510

Moving on to step 6:
When dividing 2964 by 510, we get 5 with a remainder of 414.
Write down 5 as next digit of the result. 
Result so far: 1955.0
Deduct 2550 from 2964 and we're left with 414.
Append the next digit (5) from the dividend to 414 and continue with: 4145 / 510

Moving on to step 7:
510 can be fit into 4145 8 times, resulting in a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 19558.0
Subtract 4080 from 4145 to get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 510

On to step 8:
The number 510 fits into 651 1 times, leaving a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 195581.0
Subtract 510 from 651 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 9:
When dividing 1410 by 510, we get 2 with a remainder of 390.
The number 2 becomes the next digit in our result. 
Result so far: 195581.2
If we take 1020 away from 1410, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
The number 510 fits into 3900 7 times, leaving a remainder of 330.
Record the quotient 7 as the next digit in the result. 
Result so far: 195581.27
Deduct 3570 from 3900 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 11:
If we divide 3300 by 510, we get 6 and a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 195581.276
The remainder is 240 after subtracting 3060 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
510 goes into 2400 4 times with a remainder of 360.
Use 4 as the next digit of our solution. 
Result so far: 195581.2764
Subtract 2040 from 2400 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
If we divide 3600 by 510, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 195581.27647
Subtracting 3570 from 3600 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
When dividing 300 by 510, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 195581.27647
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
3000 divided by 510 is 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 195581.2764705
The remainder is 450 after subtracting 2550 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 16:
510 goes into 4500 8 times with a remainder of 420.
Record the quotient 8 as the next digit in the result. 
Result so far: 195581.27647058
If we subtract 4080 from 4500, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Our division results in 195581.27647058 with a remaining 4.2e-07.
