We look at the division of 85100674 by 670 
The aim is to understand the frequency of 670 in 85100674.

Going ahead to step 1:
If we divide 8 by 670, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 670

Moving on to step 2:
670 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 670

Going ahead to step 3:
851 divided by 670 is 1 with a remainder of 181.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 670 from 851 and we're left with 181.
Bring next digit (0) of the dividend behind the 181 and repeat the process: 1810 / 670

Going ahead to step 4:
If we divide 1810 by 670, we get 2 and a remainder of 470.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1340 from 1810 and we're left with 470.
Append the next digit (0) from the dividend to 470 and continue with: 4700 / 670

Going ahead to step 5:
670 can be fit into 4700 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 4690 away from 4700, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 670

Going ahead to step 6:
When dividing 106 by 670, we get 0 with a remainder of 106.
Put 0 as the next digit of the answer. 
Result so far: 1270.0
The remainder is 106 after subtracting 0 from 106.
Include the next digit (7) from the dividend after 106, then repeat: 1067 / 670

Going ahead to step 7:
1067 divided by 670 is 1 with a remainder of 397.
Use 1 as the next digit of our solution. 
Result so far: 12701.0
Deduct 670 from 1067 and we're left with 397.
Take the next digit (4) from the dividend and append it to 397, then repeat: 3974 / 670

Let's proceed to step 8:
When dividing 3974 by 670, we get 5 with a remainder of 624.
Use 5 as the next digit of our solution. 
Result so far: 127015.0
Subtract 3350 from 3974 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 9:
6240 divided by 670 is 9 with a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 127015.9
If we take 6030 away from 6240, we end up 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.

Going ahead to step 10:
The number 670 fits into 2100 3 times, leaving a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 127015.93
If we subtract 2010 from 2100, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
If we divide 900 by 670, we get 1 and a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 127015.931
The remainder is 230 after subtracting 670 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
2300 divided by 670 is 3 with a remainder of 290.
Record the quotient 3 as the next digit in the result. 
Result so far: 127015.9313
If we subtract 2010 from 2300, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 13:
When dividing 2900 by 670, we get 4 with a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 127015.93134
If we take 2680 away from 2900, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
670 can be fit into 2200 3 times, resulting in a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 127015.931343
If we take 2010 away from 2200, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
670 can be fit into 1900 2 times, resulting in a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 127015.9313432
Deduct 1340 from 1900 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 16:
When dividing 5600 by 670, we get 8 with a remainder of 240.
The next digit of our result is 8. 
Result so far: 127015.93134328
If we take 5360 away from 5600, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 127015.93134328 and a remainder of 2.4e-07.
