3817980 ÷ 970 
The aim is to understand the frequency of 970 in 3817980.

Advancing to step 1:
When dividing 3 by 970, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 970

Step 2:
970 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 970

Moving on to step 3:
970 can be fit into 381 0 times, resulting in a remainder of 381.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 381 to get 381.
Include the next digit (7) from the dividend after 381, then repeat: 3817 / 970

Let's proceed to step 4:
If we divide 3817 by 970, we get 3 and a remainder of 907.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 2910 from 3817 to get 907.
Append the next digit (9) from the dividend to 907 and continue with: 9079 / 970

Step 5:
9079 divided by 970 is 9 with a remainder of 349.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 8730 from 9079 leaves us with 349.
Fetch the next digit (8) from the dividend, attach it to 349 and continue: 3498 / 970

On to step 6:
The number 970 fits into 3498 3 times, leaving a remainder of 588.
Put 3 as the next digit of the answer. 
Result so far: 393.0
The remainder is 588 after subtracting 2910 from 3498.
Take the next digit (0) from the dividend and append it to 588, then repeat: 5880 / 970

Advancing to step 7:
If we divide 5880 by 970, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 3936.0
Subtracting 5820 from 5880 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 970 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 3936.0
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 9:
970 can be fit into 6000 6 times, resulting in a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 3936.06
Subtracting 5820 from 6000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 10:
The number 970 fits into 1800 1 times, leaving a remainder of 830.
Use 1 as the next digit of our solution. 
Result so far: 3936.061
Deduct 970 from 1800 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 11:
8300 divided by 970 is 8 with a remainder of 540.
Record the quotient 8 as the next digit in the result. 
Result so far: 3936.0618
If we take 7760 away from 8300, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 12:
When dividing 5400 by 970, we get 5 with a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 3936.06185
If we subtract 4850 from 5400, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 13:
If we divide 5500 by 970, we get 5 and a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 3936.061855
Subtracting 4850 from 5500 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

After the division, we end up with 3936.061855 and a remainder of 6.5e-05.
