We're dividing 84493627 by 399 
The aim is to understand the frequency of 399 in 84493627.

Advancing to step 1:
8 divided by 399 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 399

Let's proceed to step 2:
The number 399 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (4) from the dividend after 84, then repeat: 844 / 399

On to step 3:
When dividing 844 by 399, we get 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 798 from 844 leaves us with 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 399

On to step 4:
The number 399 fits into 469 1 times, leaving a remainder of 70.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 399 from 469, we get 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 399

Going ahead to step 5:
703 divided by 399 is 1 with a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 211.0
If we subtract 399 from 703, we get 304.
Fetch the next digit (6) from the dividend, attach it to 304 and continue: 3046 / 399

Going ahead to step 6:
399 can be fit into 3046 7 times, resulting in a remainder of 253.
Write down 7 as next digit of the result. 
Result so far: 2117.0
Subtracting 2793 from 3046 leaves us with 253.
Grab the next digit (2) from the dividend, add it to 253, then carry on: 2532 / 399

Step 7:
The number 399 fits into 2532 6 times, leaving a remainder of 138.
Put 6 as the next digit of the answer. 
Result so far: 21176.0
Subtracting 2394 from 2532 leaves us with 138.
Bring next digit (7) of the dividend behind the 138 and repeat the process: 1387 / 399

On to step 8:
399 can be fit into 1387 3 times, resulting in a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 211763.0
Subtracting 1197 from 1387 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
If we divide 1900 by 399, we get 4 and a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 211763.4
Subtracting 1596 from 1900 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 10:
If we divide 3040 by 399, we get 7 and a remainder of 247.
Write down 7 as next digit of the result. 
Result so far: 211763.47
Subtracting 2793 from 3040 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Going ahead to step 11:
2470 divided by 399 is 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 211763.476
The remainder is 76 after subtracting 2394 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
399 goes into 760 1 times with a remainder of 361.
The next digit of our result is 1. 
Result so far: 211763.4761
The remainder is 361 after subtracting 399 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Moving on to step 13:
If we divide 3610 by 399, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 211763.47619
The remainder is 19 after subtracting 3591 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
If we divide 190 by 399, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 211763.47619
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 15:
The number 399 fits into 1900 4 times, leaving a remainder of 304.
Write down 4 as next digit of the result. 
Result so far: 211763.4761904
If we take 1596 away from 1900, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 16:
The number 399 fits into 3040 7 times, leaving a remainder of 247.
Write down 7 as next digit of the result. 
Result so far: 211763.47619047
Subtracting 2793 from 3040 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

The quotient of the division is 211763.47619047, and the remainder is 2.47e-07.
