Let's divide 85869780 by 602
The aim is to understand the frequency of 602 in 85869780.

Step 1:
When dividing 8 by 602, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 602

Advancing to step 2:
When dividing 85 by 602, we get 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 602

Going ahead to step 3:
The number 602 fits into 858 1 times, leaving a remainder of 256.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 602 from 858 to get 256.
Take the next digit (6) from the dividend and append it to 256, then repeat: 2566 / 602

Moving on to step 4:
2566 divided by 602 is 4 with a remainder of 158.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2408 from 2566 and we're left with 158.
Include the next digit (9) from the dividend after 158, then repeat: 1589 / 602

Moving on to step 5:
When dividing 1589 by 602, we get 2 with a remainder of 385.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we take 1204 away from 1589, we end up with 385.
Bring next digit (7) of the dividend behind the 385 and repeat the process: 3857 / 602

On to step 6:
If we divide 3857 by 602, we get 6 and a remainder of 245.
The next digit of our result is 6. 
Result so far: 1426.0
Subtract 3612 from 3857 to get 245.
Fetch the next digit (8) from the dividend, attach it to 245 and continue: 2458 / 602

Step 7:
When dividing 2458 by 602, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 14264.0
Deduct 2408 from 2458 and we're left with 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 602

Moving on to step 8:
The number 602 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 142640.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 9:
5000 divided by 602 is 8 with a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 142640.8
The remainder is 184 after subtracting 4816 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
If we divide 1840 by 602, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 142640.83
Subtract 1806 from 1840 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
602 can be fit into 340 0 times, resulting in a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 142640.83
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 12:
3400 divided by 602 is 5 with a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 142640.8305
Subtracting 3010 from 3400 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 13:
If we divide 3900 by 602, we get 6 and a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 142640.83056
Subtracting 3612 from 3900 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 14:
If we divide 2880 by 602, we get 4 and a remainder of 472.
The number 4 becomes the next digit in our result. 
Result so far: 142640.830564
Subtract 2408 from 2880 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 15:
The number 602 fits into 4720 7 times, leaving a remainder of 506.
The next digit of our result is 7. 
Result so far: 142640.8305647
If we take 4214 away from 4720, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

On to step 16:
The number 602 fits into 5060 8 times, leaving a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 142640.83056478
Deduct 4816 from 5060 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 142640.83056478, and the remainder is 2.44e-07.
