68542459 divided by 990 
Our goal is to divide 68542459 by 990.

Going ahead to step 1:
If we divide 6 by 990, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 990

Let's proceed to step 2:
990 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 990

Step 3:
The number 990 fits into 685 0 times, leaving a remainder of 685.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 685, we end up with 685.
Bring next digit (4) of the dividend behind the 685 and repeat the process: 6854 / 990

On to step 4:
990 can be fit into 6854 6 times, resulting in a remainder of 914.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 914 after subtracting 5940 from 6854.
Fetch the next digit (2) from the dividend, attach it to 914 and continue: 9142 / 990

Let's proceed to step 5:
990 goes into 9142 9 times with a remainder of 232.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 8910 from 9142 to get 232.
Bring next digit (4) of the dividend behind the 232 and repeat the process: 2324 / 990

Let's proceed to step 6:
If we divide 2324 by 990, we get 2 and a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 692.0
The remainder is 344 after subtracting 1980 from 2324.
Include the next digit (5) from the dividend after 344, then repeat: 3445 / 990

Advancing to step 7:
990 can be fit into 3445 3 times, resulting in a remainder of 475.
Write down 3 as next digit of the result. 
Result so far: 6923.0
Subtract 2970 from 3445 to get 475.
Fetch the next digit (9) from the dividend, attach it to 475 and continue: 4759 / 990

Let's proceed to step 8:
4759 divided by 990 is 4 with a remainder of 799.
The number 4 becomes the next digit in our result. 
Result so far: 69234.0
If we take 3960 away from 4759, we end up with 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Going ahead to step 9:
7990 divided by 990 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 69234.8
If we subtract 7920 from 7990, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 990 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 69234.8
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
The number 990 fits into 7000 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 69234.807
If we subtract 6930 from 7000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
990 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 69234.807
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
When dividing 7000 by 990, we get 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 69234.80707
If we subtract 6930 from 7000, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
990 can be fit into 700 0 times, resulting in a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 69234.80707
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 15:
The number 990 fits into 7000 7 times, leaving a remainder of 70.
The next digit of our result is 7. 
Result so far: 69234.8070707
Deduct 6930 from 7000 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
The number 990 fits into 700 0 times, leaving a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 69234.8070707
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 69234.8070707, with a leftover of 7e-07.
