Let's divide 78958898 by 512
We want to divide 78958898 by 512.

Moving on to step 1:
If we divide 7 by 512, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 512

Moving on to step 2:
78 divided by 512 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 512

On to step 3:
The number 512 fits into 789 1 times, leaving a remainder of 277.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 512 from 789, we get 277.
Bring next digit (5) of the dividend behind the 277 and repeat the process: 2775 / 512

Moving on to step 4:
The number 512 fits into 2775 5 times, leaving a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2560 away from 2775, we end up with 215.
Append the next digit (8) from the dividend to 215 and continue with: 2158 / 512

Advancing to step 5:
If we divide 2158 by 512, we get 4 and a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Deduct 2048 from 2158 and we're left with 110.
Append the next digit (8) from the dividend to 110 and continue with: 1108 / 512

Step 6:
512 goes into 1108 2 times with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 1542.0
If we subtract 1024 from 1108, we get 84.
Append the next digit (9) from the dividend to 84 and continue with: 849 / 512

Advancing to step 7:
The number 512 fits into 849 1 times, leaving a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 15421.0
Subtract 512 from 849 to get 337.
Bring next digit (8) of the dividend behind the 337 and repeat the process: 3378 / 512

Moving on to step 8:
3378 divided by 512 is 6 with a remainder of 306.
The number 6 becomes the next digit in our result. 
Result so far: 154216.0
If we take 3072 away from 3378, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 9:
512 goes into 3060 5 times with a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 154216.5
If we take 2560 away from 3060, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
The number 512 fits into 5000 9 times, leaving a remainder of 392.
Use 9 as the next digit of our solution. 
Result so far: 154216.59
If we take 4608 away from 5000, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 11:
512 goes into 3920 7 times with a remainder of 336.
Use 7 as the next digit of our solution. 
Result so far: 154216.597
Subtract 3584 from 3920 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 12:
512 can be fit into 3360 6 times, resulting in a remainder of 288.
Use 6 as the next digit of our solution. 
Result so far: 154216.5976
If we subtract 3072 from 3360, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
The number 512 fits into 2880 5 times, leaving a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 154216.59765
Subtracting 2560 from 2880 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
The number 512 fits into 3200 6 times, leaving a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 154216.597656
The remainder is 128 after subtracting 3072 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
When dividing 1280 by 512, we get 2 with a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 154216.5976562
Subtracting 1024 from 1280 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 16:
512 goes into 2560 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 154216.59765625
If we take 2560 away from 2560, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 154216.59765625, and the remainder is 0.0.
