Let's divide 7971657 by 574
The aim is to understand the frequency of 574 in 7971657.

Advancing to step 1:
When dividing 7 by 574, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 574

Going ahead to step 2:
The number 574 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 574

Going ahead to step 3:
If we divide 797 by 574, we get 1 and a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 574 from 797 and we're left with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 574

On to step 4:
2231 divided by 574 is 3 with a remainder of 509.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 1722 from 2231, we get 509.
Include the next digit (6) from the dividend after 509, then repeat: 5096 / 574

Step 5:
574 goes into 5096 8 times with a remainder of 504.
Write down 8 as next digit of the result. 
Result so far: 138.0
Deduct 4592 from 5096 and we're left with 504.
Grab the next digit (5) from the dividend, add it to 504, then carry on: 5045 / 574

Moving on to step 6:
If we divide 5045 by 574, we get 8 and a remainder of 453.
The number 8 becomes the next digit in our result. 
Result so far: 1388.0
Deduct 4592 from 5045 and we're left with 453.
Grab the next digit (7) from the dividend, add it to 453, then carry on: 4537 / 574

Moving on to step 7:
When dividing 4537 by 574, we get 7 with a remainder of 519.
Write down 7 as next digit of the result. 
Result so far: 13887.0
Deduct 4018 from 4537 and we're left with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 8:
5190 divided by 574 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 13887.9
If we subtract 5166 from 5190, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
574 goes into 240 0 times with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 13887.9
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 10:
The number 574 fits into 2400 4 times, leaving a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 13887.904
The remainder is 104 after subtracting 2296 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
When dividing 1040 by 574, we get 1 with a remainder of 466.
Put 1 as the next digit of the answer. 
Result so far: 13887.9041
If we take 574 away from 1040, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Let's proceed to step 12:
If we divide 4660 by 574, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 13887.90418
If we take 4592 away from 4660, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
680 divided by 574 is 1 with a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 13887.904181
If we subtract 574 from 680, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 14:
574 goes into 1060 1 times with a remainder of 486.
The number 1 becomes the next digit in our result. 
Result so far: 13887.9041811
If we subtract 574 from 1060, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

The final result is 13887.9041811 with a remainder of 4.86e-06.
