We're dividing 84122435 by 396 
The aim is to understand the frequency of 396 in 84122435.

Advancing to step 1:
The number 396 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 396

On to step 2:
84 divided by 396 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 396

Let's proceed to step 3:
396 can be fit into 841 2 times, resulting in a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 792 from 841 leaves us with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 396

Advancing to step 4:
492 divided by 396 is 1 with a remainder of 96.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 96 after subtracting 396 from 492.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 396

Advancing to step 5:
396 goes into 962 2 times with a remainder of 170.
Write down 2 as next digit of the result. 
Result so far: 212.0
The remainder is 170 after subtracting 792 from 962.
Take the next digit (4) from the dividend and append it to 170, then repeat: 1704 / 396

Step 6:
396 goes into 1704 4 times with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 2124.0
The remainder is 120 after subtracting 1584 from 1704.
Fetch the next digit (3) from the dividend, attach it to 120 and continue: 1203 / 396

Moving on to step 7:
396 can be fit into 1203 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 21243.0
Subtracting 1188 from 1203 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 396

Step 8:
If we divide 155 by 396, we get 0 and a remainder of 155.
Write down 0 as next digit of the result. 
Result so far: 212430.0
Deduct 0 from 155 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
The number 396 fits into 1550 3 times, leaving a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 212430.3
If we subtract 1188 from 1550, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 10:
The number 396 fits into 3620 9 times, leaving a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 212430.39
Subtracting 3564 from 3620 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
560 divided by 396 is 1 with a remainder of 164.
Record the quotient 1 as the next digit in the result. 
Result so far: 212430.391
Deduct 396 from 560 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 12:
When dividing 1640 by 396, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 212430.3914
Subtract 1584 from 1640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
The number 396 fits into 560 1 times, leaving a remainder of 164.
The next digit of our result is 1. 
Result so far: 212430.39141
If we take 396 away from 560, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 14:
396 can be fit into 1640 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 212430.391414
If we take 1584 away from 1640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 15:
560 divided by 396 is 1 with a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 212430.3914141
If we take 396 away from 560, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 16:
1640 divided by 396 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 212430.39141414
Subtract 1584 from 1640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 212430.39141414 with a balance of 5.6e-08.
