We're dividing 57373990 by 602 
The aim is to understand the frequency of 602 in 57373990.

Moving on to step 1:
When dividing 5 by 602, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 602

Step 2:
602 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 602

Going ahead to step 3:
The number 602 fits into 573 0 times, leaving a remainder of 573.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 573 after subtracting 0 from 573.
Bring next digit (7) of the dividend behind the 573 and repeat the process: 5737 / 602

Step 4:
602 can be fit into 5737 9 times, resulting in a remainder of 319.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 5418 from 5737 to get 319.
Fetch the next digit (3) from the dividend, attach it to 319 and continue: 3193 / 602

Let's proceed to step 5:
If we divide 3193 by 602, we get 5 and a remainder of 183.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 3010 from 3193, we get 183.
Bring next digit (9) of the dividend behind the 183 and repeat the process: 1839 / 602

On to step 6:
1839 divided by 602 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 953.0
Deduct 1806 from 1839 and we're left with 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 602

On to step 7:
602 can be fit into 339 0 times, resulting in a remainder of 339.
Record the quotient 0 as the next digit in the result. 
Result so far: 9530.0
Deduct 0 from 339 and we're left with 339.
Include the next digit (0) from the dividend after 339, then repeat: 3390 / 602

Going ahead to step 8:
The number 602 fits into 3390 5 times, leaving a remainder of 380.
Write down 5 as next digit of the result. 
Result so far: 95305.0
If we take 3010 away from 3390, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 9:
The number 602 fits into 3800 6 times, leaving a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 95305.6
If we take 3612 away from 3800, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 10:
If we divide 1880 by 602, we get 3 and a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 95305.63
Subtract 1806 from 1880 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
The number 602 fits into 740 1 times, leaving a remainder of 138.
Write down 1 as next digit of the result. 
Result so far: 95305.631
Deduct 602 from 740 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 12:
If we divide 1380 by 602, we get 2 and a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 95305.6312
If we subtract 1204 from 1380, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
When dividing 1760 by 602, we get 2 with a remainder of 556.
The number 2 becomes the next digit in our result. 
Result so far: 95305.63122
Deduct 1204 from 1760 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The quotient of the division is 95305.63122, and the remainder is 0.000556.
