90515376 ÷ 707 
The aim is to understand the frequency of 707 in 90515376.

Moving on to step 1:
707 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 707

Step 2:
If we divide 90 by 707, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 707

Going ahead to step 3:
If we divide 905 by 707, we get 1 and a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 707 from 905 and we're left with 198.
Include the next digit (1) from the dividend after 198, then repeat: 1981 / 707

Advancing to step 4:
707 can be fit into 1981 2 times, resulting in a remainder of 567.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1414 from 1981 to get 567.
Bring next digit (5) of the dividend behind the 567 and repeat the process: 5675 / 707

Advancing to step 5:
707 goes into 5675 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 128.0
Deduct 5656 from 5675 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 707

On to step 6:
The number 707 fits into 193 0 times, leaving a remainder of 193.
Use 0 as the next digit of our solution. 
Result so far: 1280.0
Subtracting 0 from 193 leaves us with 193.
Grab the next digit (7) from the dividend, add it to 193, then carry on: 1937 / 707

Advancing to step 7:
If we divide 1937 by 707, we get 2 and a remainder of 523.
Put 2 as the next digit of the answer. 
Result so far: 12802.0
Subtract 1414 from 1937 to get 523.
Take the next digit (6) from the dividend and append it to 523, then repeat: 5236 / 707

Step 8:
707 goes into 5236 7 times with a remainder of 287.
The number 7 becomes the next digit in our result. 
Result so far: 128027.0
Deduct 4949 from 5236 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 9:
If we divide 2870 by 707, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 128027.4
Subtracting 2828 from 2870 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
707 goes into 420 0 times with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 128027.4
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
If we divide 4200 by 707, we get 5 and a remainder of 665.
The next digit of our result is 5. 
Result so far: 128027.405
Subtracting 3535 from 4200 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 12:
6650 divided by 707 is 9 with a remainder of 287.
Write down 9 as next digit of the result. 
Result so far: 128027.4059
Subtract 6363 from 6650 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 13:
If we divide 2870 by 707, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 128027.40594
If we take 2828 away from 2870, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
707 goes into 420 0 times with a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 128027.40594
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 15:
707 can be fit into 4200 5 times, resulting in a remainder of 665.
Put 5 as the next digit of the answer. 
Result so far: 128027.4059405
If we subtract 3535 from 4200, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 16:
If we divide 6650 by 707, we get 9 and a remainder of 287.
Put 9 as the next digit of the answer. 
Result so far: 128027.40594059
Deduct 6363 from 6650 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

The final result is 128027.40594059 with a remainder of 2.87e-07.
