67974994 ÷ 670 
The aim is to understand the frequency of 670 in 67974994.

Advancing to step 1:
When dividing 6 by 670, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 670

Advancing to step 2:
When dividing 67 by 670, we get 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 670

Advancing to step 3:
If we divide 679 by 670, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 670 from 679 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 670

Advancing to step 4:
The number 670 fits into 97 0 times, leaving a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 97 after subtracting 0 from 97.
Fetch the next digit (4) from the dividend, attach it to 97 and continue: 974 / 670

Going ahead to step 5:
If we divide 974 by 670, we get 1 and a remainder of 304.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 670 from 974 and we're left with 304.
Append the next digit (9) from the dividend to 304 and continue with: 3049 / 670

Let's proceed to step 6:
3049 divided by 670 is 4 with a remainder of 369.
The number 4 becomes the next digit in our result. 
Result so far: 1014.0
The remainder is 369 after subtracting 2680 from 3049.
Fetch the next digit (9) from the dividend, attach it to 369 and continue: 3699 / 670

Going ahead to step 7:
If we divide 3699 by 670, we get 5 and a remainder of 349.
Record the quotient 5 as the next digit in the result. 
Result so far: 10145.0
If we subtract 3350 from 3699, we get 349.
Append the next digit (4) from the dividend to 349 and continue with: 3494 / 670

Let's proceed to step 8:
670 goes into 3494 5 times with a remainder of 144.
Write down 5 as next digit of the result. 
Result so far: 101455.0
The remainder is 144 after subtracting 3350 from 3494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
If we divide 1440 by 670, we get 2 and a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 101455.2
If we subtract 1340 from 1440, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
670 can be fit into 1000 1 times, resulting in a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 101455.21
Deduct 670 from 1000 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 11:
3300 divided by 670 is 4 with a remainder of 620.
The next digit of our result is 4. 
Result so far: 101455.214
The remainder is 620 after subtracting 2680 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 12:
6200 divided by 670 is 9 with a remainder of 170.
The next digit of our result is 9. 
Result so far: 101455.2149
The remainder is 170 after subtracting 6030 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 13:
The number 670 fits into 1700 2 times, leaving a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 101455.21492
The remainder is 360 after subtracting 1340 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 14:
670 can be fit into 3600 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 101455.214925
Subtract 3350 from 3600 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
2500 divided by 670 is 3 with a remainder of 490.
Use 3 as the next digit of our solution. 
Result so far: 101455.2149253
The remainder is 490 after subtracting 2010 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 16:
The number 670 fits into 4900 7 times, leaving a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 101455.21492537
Subtracting 4690 from 4900 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Our division results in 101455.21492537 with a remaining 2.1e-07.
