75170172 ÷ 702 
The aim is to understand the frequency of 702 in 75170172.

On to step 1:
702 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 702

Advancing to step 2:
If we divide 75 by 702, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 702

Moving on to step 3:
702 can be fit into 751 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 702 from 751 to get 49.
Bring next digit (7) of the dividend behind the 49 and repeat the process: 497 / 702

On to step 4:
If we divide 497 by 702, we get 0 and a remainder of 497.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 497, we get 497.
Bring next digit (0) of the dividend behind the 497 and repeat the process: 4970 / 702

Advancing to step 5:
4970 divided by 702 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 56 after subtracting 4914 from 4970.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 702

Step 6:
The number 702 fits into 561 0 times, leaving a remainder of 561.
Use 0 as the next digit of our solution. 
Result so far: 1070.0
If we subtract 0 from 561, we get 561.
Append the next digit (7) from the dividend to 561 and continue with: 5617 / 702

Let's proceed to step 7:
When dividing 5617 by 702, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 10708.0
The remainder is 1 after subtracting 5616 from 5617.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 702

Moving on to step 8:
When dividing 12 by 702, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 107080.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 702, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 107080.0
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 702, we get 1 and a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 107080.01
If we take 702 away from 1200, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Let's proceed to step 11:
702 goes into 4980 7 times with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 107080.017
Subtract 4914 from 4980 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
702 goes into 660 0 times with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 107080.017
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 13:
6600 divided by 702 is 9 with a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 107080.01709
Subtracting 6318 from 6600 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 14:
When dividing 2820 by 702, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 107080.017094
The remainder is 12 after subtracting 2808 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
702 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 107080.017094
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
If we divide 1200 by 702, we get 1 and a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 107080.01709401
Deduct 702 from 1200 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Our division results in 107080.01709401 with a remaining 4.98e-07.
