We're dividing 51030760 by 702 
The aim is to understand the frequency of 702 in 51030760.

Going ahead to step 1:
702 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 702

Let's proceed to step 2:
When dividing 51 by 702, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 702

On to step 3:
If we divide 510 by 702, we get 0 and a remainder of 510.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 510, we get 510.
Append the next digit (3) from the dividend to 510 and continue with: 5103 / 702

Advancing to step 4:
If we divide 5103 by 702, we get 7 and a remainder of 189.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 4914 from 5103, we get 189.
Take the next digit (0) from the dividend and append it to 189, then repeat: 1890 / 702

On to step 5:
When dividing 1890 by 702, we get 2 with a remainder of 486.
Put 2 as the next digit of the answer. 
Result so far: 72.0
If we subtract 1404 from 1890, we get 486.
Append the next digit (7) from the dividend to 486 and continue with: 4867 / 702

Going ahead to step 6:
702 can be fit into 4867 6 times, resulting in a remainder of 655.
Write down 6 as next digit of the result. 
Result so far: 726.0
Subtracting 4212 from 4867 leaves us with 655.
Include the next digit (6) from the dividend after 655, then repeat: 6556 / 702

Advancing to step 7:
6556 divided by 702 is 9 with a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 7269.0
If we subtract 6318 from 6556, we get 238.
Fetch the next digit (0) from the dividend, attach it to 238 and continue: 2380 / 702

Step 8:
2380 divided by 702 is 3 with a remainder of 274.
Use 3 as the next digit of our solution. 
Result so far: 72693.0
Subtract 2106 from 2380 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 9:
702 can be fit into 2740 3 times, resulting in a remainder of 634.
Record the quotient 3 as the next digit in the result. 
Result so far: 72693.3
Deduct 2106 from 2740 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 10:
When dividing 6340 by 702, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 72693.39
Deduct 6318 from 6340 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
702 can be fit into 220 0 times, resulting in a remainder of 220.
The next digit of our result is 0. 
Result so far: 72693.39
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
The number 702 fits into 2200 3 times, leaving a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 72693.3903
If we take 2106 away from 2200, 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.

Going ahead to step 13:
If we divide 940 by 702, we get 1 and a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 72693.39031
Deduct 702 from 940 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 14:
702 goes into 2380 3 times with a remainder of 274.
Write down 3 as next digit of the result. 
Result so far: 72693.390313
Subtract 2106 from 2380 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 15:
702 can be fit into 2740 3 times, resulting in a remainder of 634.
Put 3 as the next digit of the answer. 
Result so far: 72693.3903133
Subtracting 2106 from 2740 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

The final result is 72693.3903133 with a remainder of 6.34e-06.
