We divide 97811571 by 707
The aim is to understand the frequency of 707 in 97811571.

Step 1:
The number 707 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 707

Going ahead to step 2:
707 goes into 97 0 times with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Fetch the next digit (8) from the dividend, attach it to 97 and continue: 978 / 707

Moving on to step 3:
707 can be fit into 978 1 times, resulting in a remainder of 271.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 271 after subtracting 707 from 978.
Take the next digit (1) from the dividend and append it to 271, then repeat: 2711 / 707

Step 4:
2711 divided by 707 is 3 with a remainder of 590.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 2121 from 2711 and we're left with 590.
Fetch the next digit (1) from the dividend, attach it to 590 and continue: 5901 / 707

Let's proceed to step 5:
707 goes into 5901 8 times with a remainder of 245.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 5656 away from 5901, we end up with 245.
Take the next digit (5) from the dividend and append it to 245, then repeat: 2455 / 707

Step 6:
707 can be fit into 2455 3 times, resulting in a remainder of 334.
Write down 3 as next digit of the result. 
Result so far: 1383.0
The remainder is 334 after subtracting 2121 from 2455.
Append the next digit (7) from the dividend to 334 and continue with: 3347 / 707

Going ahead to step 7:
When dividing 3347 by 707, we get 4 with a remainder of 519.
The number 4 becomes the next digit in our result. 
Result so far: 13834.0
The remainder is 519 after subtracting 2828 from 3347.
Append the next digit (1) from the dividend to 519 and continue with: 5191 / 707

Advancing to step 8:
When dividing 5191 by 707, we get 7 with a remainder of 242.
Use 7 as the next digit of our solution. 
Result so far: 138347.0
Deduct 4949 from 5191 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 9:
707 can be fit into 2420 3 times, resulting in a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 138347.3
Subtracting 2121 from 2420 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 10:
When dividing 2990 by 707, we get 4 with a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 138347.34
If we subtract 2828 from 2990, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 11:
If we divide 1620 by 707, we get 2 and a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 138347.342
If we take 1414 away from 1620, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 12:
When dividing 2060 by 707, we get 2 with a remainder of 646.
The number 2 becomes the next digit in our result. 
Result so far: 138347.3422
If we subtract 1414 from 2060, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

The final outcome is 138347.3422, with a leftover of 0.00646.
