We divide 840630 by 67
The aim is to understand the frequency of 67 in 840630.

Advancing to step 1:
If we divide 8 by 67, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 67

Advancing to step 2:
When dividing 84 by 67, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 67 from 84 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 67

Advancing to step 3:
170 divided by 67 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 36 after subtracting 134 from 170.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 67

Moving on to step 4:
When dividing 366 by 67, we get 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 31 after subtracting 335 from 366.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 67

Let's proceed to step 5:
If we divide 313 by 67, we get 4 and a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
The remainder is 45 after subtracting 268 from 313.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 67

Advancing to step 6:
If we divide 450 by 67, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 12546.0
If we take 402 away from 450, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 67 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 12546.7
Deduct 469 from 480 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
67 can be fit into 110 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 12546.71
The remainder is 43 after subtracting 67 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 67 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 12546.716
Subtract 402 from 430 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
67 can be fit into 280 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 12546.7164
Subtract 268 from 280 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
67 can be fit into 120 1 times, resulting in a remainder of 53.
The next digit of our result is 1. 
Result so far: 12546.71641
Subtract 67 from 120 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
If we divide 530 by 67, we get 7 and a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 12546.716417
Subtract 469 from 530 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
When dividing 610 by 67, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 12546.7164179
Subtract 603 from 610 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
67 goes into 70 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12546.71641791
Deduct 67 from 70 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 12546.71641791 and a remainder of 3e-09.
