We're dividing 77189630 by 502 
The aim is to understand the frequency of 502 in 77189630.

Going ahead to step 1:
502 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 502

Let's proceed to step 2:
The number 502 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 502

On to step 3:
771 divided by 502 is 1 with a remainder of 269.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 502 from 771 leaves us with 269.
Append the next digit (8) from the dividend to 269 and continue with: 2698 / 502

On to step 4:
502 goes into 2698 5 times with a remainder of 188.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2510 from 2698 and we're left with 188.
Fetch the next digit (9) from the dividend, attach it to 188 and continue: 1889 / 502

Step 5:
If we divide 1889 by 502, we get 3 and a remainder of 383.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Subtract 1506 from 1889 to get 383.
Append the next digit (6) from the dividend to 383 and continue with: 3836 / 502

Step 6:
If we divide 3836 by 502, we get 7 and a remainder of 322.
The number 7 becomes the next digit in our result. 
Result so far: 1537.0
If we take 3514 away from 3836, we end up with 322.
Append the next digit (3) from the dividend to 322 and continue with: 3223 / 502

Going ahead to step 7:
502 goes into 3223 6 times with a remainder of 211.
The number 6 becomes the next digit in our result. 
Result so far: 15376.0
Subtracting 3012 from 3223 leaves us with 211.
Append the next digit (0) from the dividend to 211 and continue with: 2110 / 502

On to step 8:
The number 502 fits into 2110 4 times, leaving a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 153764.0
Subtracting 2008 from 2110 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 9:
502 goes into 1020 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 153764.2
Subtract 1004 from 1020 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
502 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 153764.2
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
If we divide 1600 by 502, we get 3 and a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 153764.203
If we take 1506 away from 1600, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
502 goes into 940 1 times with a remainder of 438.
Use 1 as the next digit of our solution. 
Result so far: 153764.2031
Deduct 502 from 940 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 13:
502 goes into 4380 8 times with a remainder of 364.
The next digit of our result is 8. 
Result so far: 153764.20318
If we take 4016 away from 4380, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 14:
3640 divided by 502 is 7 with a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 153764.203187
Deduct 3514 from 3640 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 15:
502 goes into 1260 2 times with a remainder of 256.
The number 2 becomes the next digit in our result. 
Result so far: 153764.2031872
Subtracting 1004 from 1260 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
The number 502 fits into 2560 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 153764.20318725
The remainder is 50 after subtracting 2510 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 153764.20318725, and the remainder is 5e-08.
