17026390 ÷ 963 
The aim is to understand the frequency of 963 in 17026390.

Going ahead to step 1:
When dividing 1 by 963, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 963

Moving on to step 2:
17 divided by 963 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 963

Let's proceed to step 3:
The number 963 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 170, we get 170.
Include the next digit (2) from the dividend after 170, then repeat: 1702 / 963

On to step 4:
963 goes into 1702 1 times with a remainder of 739.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 963 from 1702, we get 739.
Fetch the next digit (6) from the dividend, attach it to 739 and continue: 7396 / 963

On to step 5:
If we divide 7396 by 963, we get 7 and a remainder of 655.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 6741 from 7396 and we're left with 655.
Append the next digit (3) from the dividend to 655 and continue with: 6553 / 963

Moving on to step 6:
When dividing 6553 by 963, we get 6 with a remainder of 775.
The next digit of our result is 6. 
Result so far: 176.0
If we subtract 5778 from 6553, we get 775.
Take the next digit (9) from the dividend and append it to 775, then repeat: 7759 / 963

Going ahead to step 7:
The number 963 fits into 7759 8 times, leaving a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 1768.0
Subtracting 7704 from 7759 leaves us with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 963

Step 8:
If we divide 550 by 963, we get 0 and a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 17680.0
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 9:
When dividing 5500 by 963, we get 5 with a remainder of 685.
Write down 5 as next digit of the result. 
Result so far: 17680.5
If we take 4815 away from 5500, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 10:
963 can be fit into 6850 7 times, resulting in a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 17680.57
If we take 6741 away from 6850, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 11:
1090 divided by 963 is 1 with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 17680.571
If we take 963 away from 1090, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
963 can be fit into 1270 1 times, resulting in a remainder of 307.
The next digit of our result is 1. 
Result so far: 17680.5711
If we take 963 away from 1270, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The final result is 17680.5711 with a remainder of 0.00307.
