We're dividing 57525509 by 670 
The aim is to understand the frequency of 670 in 57525509.

Going ahead to step 1:
670 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 670

On to step 2:
670 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 670

Advancing to step 3:
575 divided by 670 is 0 with a remainder of 575.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 575 to get 575.
Grab the next digit (2) from the dividend, add it to 575, then carry on: 5752 / 670

Moving on to step 4:
If we divide 5752 by 670, we get 8 and a remainder of 392.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 5360 from 5752, we get 392.
Append the next digit (5) from the dividend to 392 and continue with: 3925 / 670

Let's proceed to step 5:
The number 670 fits into 3925 5 times, leaving a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtract 3350 from 3925 to get 575.
Grab the next digit (5) from the dividend, add it to 575, then carry on: 5755 / 670

Advancing to step 6:
The number 670 fits into 5755 8 times, leaving a remainder of 395.
Write down 8 as next digit of the result. 
Result so far: 858.0
Deduct 5360 from 5755 and we're left with 395.
Fetch the next digit (0) from the dividend, attach it to 395 and continue: 3950 / 670

Advancing to step 7:
3950 divided by 670 is 5 with a remainder of 600.
The next digit of our result is 5. 
Result so far: 8585.0
Subtracting 3350 from 3950 leaves us with 600.
Take the next digit (9) from the dividend and append it to 600, then repeat: 6009 / 670

Step 8:
670 can be fit into 6009 8 times, resulting in a remainder of 649.
The next digit of our result is 8. 
Result so far: 85858.0
If we take 5360 away from 6009, we end up with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 9:
670 can be fit into 6490 9 times, resulting in a remainder of 460.
The next digit of our result is 9. 
Result so far: 85858.9
If we take 6030 away from 6490, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
670 goes into 4600 6 times with a remainder of 580.
Record the quotient 6 as the next digit in the result. 
Result so far: 85858.96
If we subtract 4020 from 4600, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 11:
When dividing 5800 by 670, we get 8 with a remainder of 440.
The next digit of our result is 8. 
Result so far: 85858.968
Subtract 5360 from 5800 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
670 goes into 4400 6 times with a remainder of 380.
Use 6 as the next digit of our solution. 
Result so far: 85858.9686
Deduct 4020 from 4400 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
670 can be fit into 3800 5 times, resulting in a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 85858.96865
Deduct 3350 from 3800 and we're left 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 14:
When dividing 4500 by 670, we get 6 with a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 85858.968656
If we take 4020 away from 4500, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 15:
4800 divided by 670 is 7 with a remainder of 110.
Write down 7 as next digit of the result. 
Result so far: 85858.9686567
If we take 4690 away from 4800, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
1100 divided by 670 is 1 with a remainder of 430.
Put 1 as the next digit of the answer. 
Result so far: 85858.96865671
Subtract 670 from 1100 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final result is 85858.96865671 with a remainder of 4.3e-07.
