Let's divide 79833681 by 400
The aim is to understand the frequency of 400 in 79833681.

On to step 1:
7 divided by 400 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 400

Let's proceed to step 2:
400 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 400

Advancing to step 3:
400 goes into 798 1 times with a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 400 from 798 leaves us with 398.
Include the next digit (3) from the dividend after 398, then repeat: 3983 / 400

Step 4:
If we divide 3983 by 400, we get 9 and a remainder of 383.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 3600 from 3983, we get 383.
Take the next digit (3) from the dividend and append it to 383, then repeat: 3833 / 400

Advancing to step 5:
3833 divided by 400 is 9 with a remainder of 233.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
The remainder is 233 after subtracting 3600 from 3833.
Include the next digit (6) from the dividend after 233, then repeat: 2336 / 400

On to step 6:
The number 400 fits into 2336 5 times, leaving a remainder of 336.
The number 5 becomes the next digit in our result. 
Result so far: 1995.0
Subtracting 2000 from 2336 leaves us with 336.
Include the next digit (8) from the dividend after 336, then repeat: 3368 / 400

Step 7:
3368 divided by 400 is 8 with a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 19958.0
The remainder is 168 after subtracting 3200 from 3368.
Bring next digit (1) of the dividend behind the 168 and repeat the process: 1681 / 400

Advancing to step 8:
400 can be fit into 1681 4 times, resulting in a remainder of 81.
The next digit of our result is 4. 
Result so far: 199584.0
Subtracting 1600 from 1681 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
810 divided by 400 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 199584.2
The remainder is 10 after subtracting 800 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 400, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 199584.2
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
400 goes into 1000 2 times with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 199584.202
Subtracting 800 from 1000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 199584.2025
Subtracting 2000 from 2000 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 199584.2025
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
0 divided by 400 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 199584.2025
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 199584.2025, with a leftover of 0.0.
