We divide 7987922 by 381
The aim is to understand the frequency of 381 in 7987922.

Step 1:
When dividing 7 by 381, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 381

Let's proceed to step 2:
381 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 381

Going ahead to step 3:
798 divided by 381 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 762 from 798 to get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 381

Let's proceed to step 4:
The number 381 fits into 367 0 times, leaving a remainder of 367.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 367, we end up with 367.
Take the next digit (9) from the dividend and append it to 367, then repeat: 3679 / 381

Let's proceed to step 5:
If we divide 3679 by 381, we get 9 and a remainder of 250.
Use 9 as the next digit of our solution. 
Result so far: 209.0
Subtract 3429 from 3679 to get 250.
Append the next digit (2) from the dividend to 250 and continue with: 2502 / 381

Let's proceed to step 6:
381 goes into 2502 6 times with a remainder of 216.
The next digit of our result is 6. 
Result so far: 2096.0
Deduct 2286 from 2502 and we're left with 216.
Grab the next digit (2) from the dividend, add it to 216, then carry on: 2162 / 381

Step 7:
2162 divided by 381 is 5 with a remainder of 257.
The number 5 becomes the next digit in our result. 
Result so far: 20965.0
Subtract 1905 from 2162 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 8:
If we divide 2570 by 381, we get 6 and a remainder of 284.
The next digit of our result is 6. 
Result so far: 20965.6
If we subtract 2286 from 2570, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 9:
2840 divided by 381 is 7 with a remainder of 173.
The number 7 becomes the next digit in our result. 
Result so far: 20965.67
If we take 2667 away from 2840, we end up with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 10:
The number 381 fits into 1730 4 times, leaving a remainder of 206.
Write down 4 as next digit of the result. 
Result so far: 20965.674
If we take 1524 away from 1730, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 11:
381 goes into 2060 5 times with a remainder of 155.
The next digit of our result is 5. 
Result so far: 20965.6745
If we subtract 1905 from 2060, we get 155.
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 12:
When dividing 1550 by 381, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 20965.67454
Subtract 1524 from 1550 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
260 divided by 381 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 20965.67454
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
2600 divided by 381 is 6 with a remainder of 314.
Write down 6 as next digit of the result. 
Result so far: 20965.6745406
If we subtract 2286 from 2600, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 15:
381 can be fit into 3140 8 times, resulting in a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 20965.67454068
The remainder is 92 after subtracting 3048 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 20965.67454068, with a leftover of 9.2e-08.
