68147636 divided by 397 
The aim is to understand the frequency of 397 in 68147636.

On to step 1:
397 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 397

Moving on to step 2:
397 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 397

Let's proceed to step 3:
When dividing 681 by 397, we get 1 with a remainder of 284.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 397 from 681, we get 284.
Fetch the next digit (4) from the dividend, attach it to 284 and continue: 2844 / 397

Going ahead to step 4:
The number 397 fits into 2844 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 2779 from 2844 and we're left with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 397

Going ahead to step 5:
The number 397 fits into 657 1 times, leaving a remainder of 260.
Write down 1 as next digit of the result. 
Result so far: 171.0
Deduct 397 from 657 and we're left with 260.
Bring next digit (6) of the dividend behind the 260 and repeat the process: 2606 / 397

Going ahead to step 6:
397 goes into 2606 6 times with a remainder of 224.
Put 6 as the next digit of the answer. 
Result so far: 1716.0
If we subtract 2382 from 2606, we get 224.
Grab the next digit (3) from the dividend, add it to 224, then carry on: 2243 / 397

On to step 7:
2243 divided by 397 is 5 with a remainder of 258.
The next digit of our result is 5. 
Result so far: 17165.0
Subtract 1985 from 2243 to get 258.
Take the next digit (6) from the dividend and append it to 258, then repeat: 2586 / 397

Advancing to step 8:
When dividing 2586 by 397, we get 6 with a remainder of 204.
Use 6 as the next digit of our solution. 
Result so far: 171656.0
If we subtract 2382 from 2586, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 9:
2040 divided by 397 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 171656.5
The remainder is 55 after subtracting 1985 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
The number 397 fits into 550 1 times, leaving a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 171656.51
Subtracting 397 from 550 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 11:
If we divide 1530 by 397, we get 3 and a remainder of 339.
The next digit of our result is 3. 
Result so far: 171656.513
If we subtract 1191 from 1530, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 12:
397 can be fit into 3390 8 times, resulting in a remainder of 214.
The next digit of our result is 8. 
Result so far: 171656.5138
The remainder is 214 after subtracting 3176 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
397 can be fit into 2140 5 times, resulting in a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 171656.51385
The remainder is 155 after subtracting 1985 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 14:
The number 397 fits into 1550 3 times, leaving a remainder of 359.
The next digit of our result is 3. 
Result so far: 171656.513853
Deduct 1191 from 1550 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 15:
397 goes into 3590 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 171656.5138539
The remainder is 17 after subtracting 3573 from 3590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 16:
When dividing 170 by 397, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 171656.5138539
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 171656.5138539, with a leftover of 1.7e-07.
