62159703 divided by 397 
The aim is to understand the frequency of 397 in 62159703.

On to step 1:
397 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 397

Going ahead to step 2:
When dividing 62 by 397, we get 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 397

On to step 3:
621 divided by 397 is 1 with a remainder of 224.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 397 away from 621, we end up with 224.
Take the next digit (5) from the dividend and append it to 224, then repeat: 2245 / 397

Moving on to step 4:
397 goes into 2245 5 times with a remainder of 260.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 260 after subtracting 1985 from 2245.
Take the next digit (9) from the dividend and append it to 260, then repeat: 2609 / 397

Going ahead to step 5:
The number 397 fits into 2609 6 times, leaving a remainder of 227.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 2382 from 2609 leaves us with 227.
Grab the next digit (7) from the dividend, add it to 227, then carry on: 2277 / 397

Step 6:
The number 397 fits into 2277 5 times, leaving a remainder of 292.
Put 5 as the next digit of the answer. 
Result so far: 1565.0
Subtract 1985 from 2277 to get 292.
Bring next digit (0) of the dividend behind the 292 and repeat the process: 2920 / 397

Advancing to step 7:
When dividing 2920 by 397, we get 7 with a remainder of 141.
Write down 7 as next digit of the result. 
Result so far: 15657.0
If we take 2779 away from 2920, we end up with 141.
Grab the next digit (3) from the dividend, add it to 141, then carry on: 1413 / 397

Let's proceed to step 8:
397 can be fit into 1413 3 times, resulting in a remainder of 222.
Use 3 as the next digit of our solution. 
Result so far: 156573.0
The remainder is 222 after subtracting 1191 from 1413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 9:
2220 divided by 397 is 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 156573.5
Deduct 1985 from 2220 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 10:
The number 397 fits into 2350 5 times, leaving a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 156573.55
If we take 1985 away from 2350, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

After the division, we end up with 156573.55 and a remainder of 0.365.
