Let's divide 45398698 by 990
We're looking to find how many times 990 goes into 45398698.

Moving on to step 1:
4 divided by 990 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 990

Step 2:
990 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 990

Let's proceed to step 3:
990 can be fit into 453 0 times, resulting in a remainder of 453.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 453, we end up with 453.
Fetch the next digit (9) from the dividend, attach it to 453 and continue: 4539 / 990

On to step 4:
When dividing 4539 by 990, we get 4 with a remainder of 579.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3960 from 4539 and we're left with 579.
Take the next digit (8) from the dividend and append it to 579, then repeat: 5798 / 990

On to step 5:
When dividing 5798 by 990, we get 5 with a remainder of 848.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 4950 from 5798, we get 848.
Grab the next digit (6) from the dividend, add it to 848, then carry on: 8486 / 990

Let's proceed to step 6:
990 goes into 8486 8 times with a remainder of 566.
The number 8 becomes the next digit in our result. 
Result so far: 458.0
Deduct 7920 from 8486 and we're left with 566.
Bring next digit (9) of the dividend behind the 566 and repeat the process: 5669 / 990

Step 7:
990 can be fit into 5669 5 times, resulting in a remainder of 719.
Use 5 as the next digit of our solution. 
Result so far: 4585.0
Deduct 4950 from 5669 and we're left with 719.
Include the next digit (8) from the dividend after 719, then repeat: 7198 / 990

Moving on to step 8:
If we divide 7198 by 990, we get 7 and a remainder of 268.
Record the quotient 7 as the next digit in the result. 
Result so far: 45857.0
Subtract 6930 from 7198 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 9:
2680 divided by 990 is 2 with a remainder of 700.
Put 2 as the next digit of the answer. 
Result so far: 45857.2
If we take 1980 away from 2680, 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.

Step 10:
990 goes into 7000 7 times with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 45857.27
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.

Step 11:
The number 990 fits into 700 0 times, leaving a remainder of 700.
The next digit of our result is 0. 
Result so far: 45857.27
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.

Advancing to step 12:
990 can be fit into 7000 7 times, resulting in a remainder of 70.
The next digit of our result is 7. 
Result so far: 45857.2707
Subtract 6930 from 7000 to 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.

Moving on to step 13:
If we divide 700 by 990, we get 0 and a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 45857.2707
Deduct 0 from 700 and we're left 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.

Step 14:
If we divide 7000 by 990, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 45857.270707
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.

Advancing to step 15:
When dividing 700 by 990, we get 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 45857.270707
Deduct 0 from 700 and we're left 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.

Step 16:
990 goes into 7000 7 times with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 45857.27070707
The remainder is 70 after subtracting 6930 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 45857.27070707 with a remainder of 7e-08.
