We're dividing 83627821 by 670 
The aim is to understand the frequency of 670 in 83627821.

Step 1:
670 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 670

On to step 2:
670 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 670

On to step 3:
When dividing 836 by 670, we get 1 with a remainder of 166.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 670 from 836 to get 166.
Include the next digit (2) from the dividend after 166, then repeat: 1662 / 670

On to step 4:
The number 670 fits into 1662 2 times, leaving a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1340 from 1662 and we're left with 322.
Append the next digit (7) from the dividend to 322 and continue with: 3227 / 670

Advancing to step 5:
670 goes into 3227 4 times with a remainder of 547.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we subtract 2680 from 3227, we get 547.
Bring next digit (8) of the dividend behind the 547 and repeat the process: 5478 / 670

Going ahead to step 6:
670 goes into 5478 8 times with a remainder of 118.
The next digit of our result is 8. 
Result so far: 1248.0
Subtracting 5360 from 5478 leaves us with 118.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 670

Moving on to step 7:
If we divide 1182 by 670, we get 1 and a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 12481.0
Subtract 670 from 1182 to get 512.
Append the next digit (1) from the dividend to 512 and continue with: 5121 / 670

Going ahead to step 8:
670 can be fit into 5121 7 times, resulting in a remainder of 431.
Use 7 as the next digit of our solution. 
Result so far: 124817.0
Subtract 4690 from 5121 to get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 9:
4310 divided by 670 is 6 with a remainder of 290.
Record the quotient 6 as the next digit in the result. 
Result so far: 124817.6
Deduct 4020 from 4310 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
If we divide 2900 by 670, we get 4 and a remainder of 220.
The number 4 becomes the next digit in our result. 
Result so far: 124817.64
The remainder is 220 after subtracting 2680 from 2900.
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 11:
670 can be fit into 2200 3 times, resulting in a remainder of 190.
Use 3 as the next digit of our solution. 
Result so far: 124817.643
Subtracting 2010 from 2200 leaves us 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 12:
670 can be fit into 1900 2 times, resulting in a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 124817.6432
If we subtract 1340 from 1900, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
The number 670 fits into 5600 8 times, leaving a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 124817.64328
If we subtract 5360 from 5600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
670 goes into 2400 3 times with a remainder of 390.
The next digit of our result is 3. 
Result so far: 124817.643283
The remainder is 390 after subtracting 2010 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 15:
3900 divided by 670 is 5 with a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 124817.6432835
Deduct 3350 from 3900 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 16:
5500 divided by 670 is 8 with a remainder of 140.
Put 8 as the next digit of the answer. 
Result so far: 124817.64328358
If we take 5360 away from 5500, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 124817.64328358 with a remaining 1.4e-07.
