89485420 divided by 381 
The aim is to understand the frequency of 381 in 89485420.

On to step 1:
381 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 381

Moving on to step 2:
The number 381 fits into 89 0 times, leaving a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 381

On to step 3:
381 goes into 894 2 times with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 762 from 894 leaves us with 132.
Append the next digit (8) from the dividend to 132 and continue with: 1328 / 381

Step 4:
381 goes into 1328 3 times with a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 1143 from 1328 to get 185.
Fetch the next digit (5) from the dividend, attach it to 185 and continue: 1855 / 381

Going ahead to step 5:
1855 divided by 381 is 4 with a remainder of 331.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Deduct 1524 from 1855 and we're left with 331.
Append the next digit (4) from the dividend to 331 and continue with: 3314 / 381

Let's proceed to step 6:
3314 divided by 381 is 8 with a remainder of 266.
Use 8 as the next digit of our solution. 
Result so far: 2348.0
Deduct 3048 from 3314 and we're left with 266.
Grab the next digit (2) from the dividend, add it to 266, then carry on: 2662 / 381

Step 7:
2662 divided by 381 is 6 with a remainder of 376.
The next digit of our result is 6. 
Result so far: 23486.0
If we take 2286 away from 2662, we end up with 376.
Bring next digit (0) of the dividend behind the 376 and repeat the process: 3760 / 381

Moving on to step 8:
The number 381 fits into 3760 9 times, leaving a remainder of 331.
Record the quotient 9 as the next digit in the result. 
Result so far: 234869.0
The remainder is 331 after subtracting 3429 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 9:
3310 divided by 381 is 8 with a remainder of 262.
Record the quotient 8 as the next digit in the result. 
Result so far: 234869.8
If we subtract 3048 from 3310, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 10:
The number 381 fits into 2620 6 times, leaving a remainder of 334.
Record the quotient 6 as the next digit in the result. 
Result so far: 234869.86
Subtract 2286 from 2620 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 11:
3340 divided by 381 is 8 with a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 234869.868
The remainder is 292 after subtracting 3048 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 12:
381 can be fit into 2920 7 times, resulting in a remainder of 253.
The next digit of our result is 7. 
Result so far: 234869.8687
If we subtract 2667 from 2920, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 13:
381 can be fit into 2530 6 times, resulting in a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 234869.86876
The remainder is 244 after subtracting 2286 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 14:
381 can be fit into 2440 6 times, resulting in a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 234869.868766
Deduct 2286 from 2440 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 234869.868766 and a remainder of 1.54e-05.
