We look at the division of 67774211 by 397 
The aim is to understand the frequency of 397 in 67774211.

Going ahead to step 1:
When dividing 6 by 397, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 397

Advancing to step 2:
397 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 397

Moving on to step 3:
677 divided by 397 is 1 with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 397 from 677 and we're left with 280.
Take the next digit (7) from the dividend and append it to 280, then repeat: 2807 / 397

Step 4:
397 goes into 2807 7 times with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 2779 away from 2807, we end up with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 397

On to step 5:
If we divide 284 by 397, we get 0 and a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtract 0 from 284 to get 284.
Take the next digit (2) from the dividend and append it to 284, then repeat: 2842 / 397

Going ahead to step 6:
397 goes into 2842 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 1707.0
Subtract 2779 from 2842 to get 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 397

Advancing to step 7:
631 divided by 397 is 1 with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 17071.0
Subtract 397 from 631 to get 234.
Bring next digit (1) of the dividend behind the 234 and repeat the process: 2341 / 397

On to step 8:
When dividing 2341 by 397, we get 5 with a remainder of 356.
Write down 5 as next digit of the result. 
Result so far: 170715.0
Subtracting 1985 from 2341 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 9:
When dividing 3560 by 397, we get 8 with a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 170715.8
If we take 3176 away from 3560, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 10:
397 can be fit into 3840 9 times, resulting in a remainder of 267.
Use 9 as the next digit of our solution. 
Result so far: 170715.89
Deduct 3573 from 3840 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 11:
If we divide 2670 by 397, we get 6 and a remainder of 288.
Write down 6 as next digit of the result. 
Result so far: 170715.896
Subtract 2382 from 2670 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
397 goes into 2880 7 times with a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 170715.8967
Deduct 2779 from 2880 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 13:
The number 397 fits into 1010 2 times, leaving a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 170715.89672
Deduct 794 from 1010 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 14:
The number 397 fits into 2160 5 times, leaving a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 170715.896725
Subtracting 1985 from 2160 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 15:
The number 397 fits into 1750 4 times, leaving a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 170715.8967254
Deduct 1588 from 1750 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 16:
When dividing 1620 by 397, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 170715.89672544
Deduct 1588 from 1620 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 170715.89672544, and the remainder is 3.2e-08.
