We're dividing 20517798 by 702 
The aim is to understand the frequency of 702 in 20517798.

On to step 1:
702 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 702

On to step 2:
The number 702 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 702

Advancing to step 3:
If we divide 205 by 702, we get 0 and a remainder of 205.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 205 leaves us with 205.
Grab the next digit (1) from the dividend, add it to 205, then carry on: 2051 / 702

On to step 4:
702 can be fit into 2051 2 times, resulting in a remainder of 647.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 647 after subtracting 1404 from 2051.
Include the next digit (7) from the dividend after 647, then repeat: 6477 / 702

Advancing to step 5:
702 can be fit into 6477 9 times, resulting in a remainder of 159.
The next digit of our result is 9. 
Result so far: 29.0
If we subtract 6318 from 6477, we get 159.
Take the next digit (7) from the dividend and append it to 159, then repeat: 1597 / 702

Let's proceed to step 6:
When dividing 1597 by 702, we get 2 with a remainder of 193.
Write down 2 as next digit of the result. 
Result so far: 292.0
Deduct 1404 from 1597 and we're left with 193.
Include the next digit (9) from the dividend after 193, then repeat: 1939 / 702

Advancing to step 7:
The number 702 fits into 1939 2 times, leaving a remainder of 535.
The number 2 becomes the next digit in our result. 
Result so far: 2922.0
The remainder is 535 after subtracting 1404 from 1939.
Include the next digit (8) from the dividend after 535, then repeat: 5358 / 702

Moving on to step 8:
702 can be fit into 5358 7 times, resulting in a remainder of 444.
Write down 7 as next digit of the result. 
Result so far: 29227.0
Subtracting 4914 from 5358 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 9:
702 goes into 4440 6 times with a remainder of 228.
Write down 6 as next digit of the result. 
Result so far: 29227.6
If we take 4212 away from 4440, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
702 goes into 2280 3 times with a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 29227.63
If we take 2106 away from 2280, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 11:
The number 702 fits into 1740 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 29227.632
Deduct 1404 from 1740 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
When dividing 3360 by 702, we get 4 with a remainder of 552.
The next digit of our result is 4. 
Result so far: 29227.6324
Subtract 2808 from 3360 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 13:
5520 divided by 702 is 7 with a remainder of 606.
The next digit of our result is 7. 
Result so far: 29227.63247
If we take 4914 away from 5520, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Moving on to step 14:
When dividing 6060 by 702, we get 8 with a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 29227.632478
Subtracting 5616 from 6060 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 15:
702 goes into 4440 6 times with a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 29227.6324786
If we take 4212 away from 4440, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 16:
If we divide 2280 by 702, we get 3 and a remainder of 174.
Use 3 as the next digit of our solution. 
Result so far: 29227.63247863
If we take 2106 away from 2280, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Our division results in 29227.63247863 with a remaining 1.74e-07.
