83570490 ÷ 396 
The aim is to understand the frequency of 396 in 83570490.

Advancing to step 1:
396 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 396

Going ahead to step 2:
The number 396 fits into 83 0 times, leaving a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 396

Advancing to step 3:
The number 396 fits into 835 2 times, leaving a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 792 from 835, we get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 396

Step 4:
396 goes into 437 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 396 away from 437, we end up with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 396

Moving on to step 5:
If we divide 410 by 396, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 211.0
Subtracting 396 from 410 leaves us with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 396

Step 6:
If we divide 144 by 396, we get 0 and a remainder of 144.
Use 0 as the next digit of our solution. 
Result so far: 2110.0
Deduct 0 from 144 and we're left with 144.
Bring next digit (9) of the dividend behind the 144 and repeat the process: 1449 / 396

On to step 7:
The number 396 fits into 1449 3 times, leaving a remainder of 261.
Put 3 as the next digit of the answer. 
Result so far: 21103.0
Subtract 1188 from 1449 to get 261.
Include the next digit (0) from the dividend after 261, then repeat: 2610 / 396

Moving on to step 8:
The number 396 fits into 2610 6 times, leaving a remainder of 234.
Put 6 as the next digit of the answer. 
Result so far: 211036.0
Deduct 2376 from 2610 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
396 can be fit into 2340 5 times, resulting in a remainder of 360.
The next digit of our result is 5. 
Result so far: 211036.5
If we subtract 1980 from 2340, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 396, we get 9 and a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 211036.59
If we subtract 3564 from 3600, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
396 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 211036.59
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
396 goes into 3600 9 times with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 211036.5909
If we subtract 3564 from 3600, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
If we divide 360 by 396, we get 0 and a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 211036.5909
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
When dividing 3600 by 396, we get 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 211036.590909
If we take 3564 away from 3600, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 15:
396 goes into 360 0 times with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 211036.590909
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 16:
3600 divided by 396 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 211036.59090909
Deduct 3564 from 3600 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 211036.59090909 with a balance of 3.6e-08.
