We're dividing 71886757 by 670 
The aim is to understand the frequency of 670 in 71886757.

Advancing to step 1:
When dividing 7 by 670, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 670

Let's proceed to step 2:
71 divided by 670 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 670

Let's proceed to step 3:
670 can be fit into 718 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 670 from 718, we get 48.
Include the next digit (8) from the dividend after 48, then repeat: 488 / 670

On to step 4:
The number 670 fits into 488 0 times, leaving a remainder of 488.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 488 leaves us with 488.
Grab the next digit (6) from the dividend, add it to 488, then carry on: 4886 / 670

Let's proceed to step 5:
4886 divided by 670 is 7 with a remainder of 196.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 4690 from 4886 leaves us with 196.
Take the next digit (7) from the dividend and append it to 196, then repeat: 1967 / 670

On to step 6:
670 can be fit into 1967 2 times, resulting in a remainder of 627.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
If we take 1340 away from 1967, we end up with 627.
Include the next digit (5) from the dividend after 627, then repeat: 6275 / 670

Moving on to step 7:
6275 divided by 670 is 9 with a remainder of 245.
Put 9 as the next digit of the answer. 
Result so far: 10729.0
Subtract 6030 from 6275 to get 245.
Fetch the next digit (7) from the dividend, attach it to 245 and continue: 2457 / 670

Let's proceed to step 8:
When dividing 2457 by 670, we get 3 with a remainder of 447.
Record the quotient 3 as the next digit in the result. 
Result so far: 107293.0
Subtracting 2010 from 2457 leaves us with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 9:
4470 divided by 670 is 6 with a remainder of 450.
Put 6 as the next digit of the answer. 
Result so far: 107293.6
Subtracting 4020 from 4470 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 10:
670 goes into 4500 6 times with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 107293.66
The remainder is 480 after subtracting 4020 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 107293.66, and the remainder is 0.48.
