45734638 ÷ 990 
The aim is to understand the frequency of 990 in 45734638.

On to step 1:
990 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 990

Advancing to step 2:
The number 990 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 990

Going ahead to step 3:
990 goes into 457 0 times with a remainder of 457.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 457 leaves us with 457.
Grab the next digit (3) from the dividend, add it to 457, then carry on: 4573 / 990

On to step 4:
The number 990 fits into 4573 4 times, leaving a remainder of 613.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3960 from 4573, we get 613.
Grab the next digit (4) from the dividend, add it to 613, then carry on: 6134 / 990

Let's proceed to step 5:
When dividing 6134 by 990, we get 6 with a remainder of 194.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 194 after subtracting 5940 from 6134.
Fetch the next digit (6) from the dividend, attach it to 194 and continue: 1946 / 990

Let's proceed to step 6:
990 can be fit into 1946 1 times, resulting in a remainder of 956.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtract 990 from 1946 to get 956.
Fetch the next digit (3) from the dividend, attach it to 956 and continue: 9563 / 990

Advancing to step 7:
The number 990 fits into 9563 9 times, leaving a remainder of 653.
Use 9 as the next digit of our solution. 
Result so far: 4619.0
If we take 8910 away from 9563, we end up with 653.
Append the next digit (8) from the dividend to 653 and continue with: 6538 / 990

Moving on to step 8:
990 goes into 6538 6 times with a remainder of 598.
Put 6 as the next digit of the answer. 
Result so far: 46196.0
Subtracting 5940 from 6538 leaves us with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 9:
When dividing 5980 by 990, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 46196.6
Subtract 5940 from 5980 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
990 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 46196.6
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
The number 990 fits into 4000 4 times, leaving a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 46196.604
The remainder is 40 after subtracting 3960 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
If we divide 400 by 990, we get 0 and a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 46196.604
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
4000 divided by 990 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 46196.60404
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
The number 990 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 46196.60404
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 15:
990 can be fit into 4000 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 46196.6040404
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 16:
990 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 46196.6040404
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 46196.6040404, with a leftover of 4e-07.
