We divide 99211517 by 789
Our goal is to divide 99211517 by 789.

Step 1:
789 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 789

Step 2:
When dividing 99 by 789, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 789

Advancing to step 3:
The number 789 fits into 992 1 times, leaving a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 789 from 992, we get 203.
Append the next digit (1) from the dividend to 203 and continue with: 2031 / 789

On to step 4:
789 can be fit into 2031 2 times, resulting in a remainder of 453.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1578 from 2031, we get 453.
Fetch the next digit (1) from the dividend, attach it to 453 and continue: 4531 / 789

Step 5:
789 can be fit into 4531 5 times, resulting in a remainder of 586.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 3945 from 4531 and we're left with 586.
Bring next digit (5) of the dividend behind the 586 and repeat the process: 5865 / 789

Moving on to step 6:
5865 divided by 789 is 7 with a remainder of 342.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
Subtract 5523 from 5865 to get 342.
Include the next digit (1) from the dividend after 342, then repeat: 3421 / 789

Step 7:
3421 divided by 789 is 4 with a remainder of 265.
Use 4 as the next digit of our solution. 
Result so far: 12574.0
If we take 3156 away from 3421, we end up with 265.
Take the next digit (7) from the dividend and append it to 265, then repeat: 2657 / 789

Going ahead to step 8:
789 goes into 2657 3 times with a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 125743.0
If we subtract 2367 from 2657, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 9:
If we divide 2900 by 789, we get 3 and a remainder of 533.
Use 3 as the next digit of our solution. 
Result so far: 125743.3
Subtract 2367 from 2900 to get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

On to step 10:
When dividing 5330 by 789, we get 6 with a remainder of 596.
Use 6 as the next digit of our solution. 
Result so far: 125743.36
If we take 4734 away from 5330, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 11:
5960 divided by 789 is 7 with a remainder of 437.
Put 7 as the next digit of the answer. 
Result so far: 125743.367
The remainder is 437 after subtracting 5523 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

On to step 12:
789 can be fit into 4370 5 times, resulting in a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 125743.3675
The remainder is 425 after subtracting 3945 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 13:
The number 789 fits into 4250 5 times, leaving a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 125743.36755
The remainder is 305 after subtracting 3945 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 125743.36755 and a remainder of 0.000305.
