68269393 ÷ 400 
The aim is to understand the frequency of 400 in 68269393.

Going ahead to step 1:
6 divided by 400 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 400

Going ahead to step 2:
68 divided by 400 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 400

Step 3:
400 can be fit into 682 1 times, resulting in a remainder of 282.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 282 after subtracting 400 from 682.
Append the next digit (6) from the dividend to 282 and continue with: 2826 / 400

Step 4:
2826 divided by 400 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 2800 from 2826, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 400

Moving on to step 5:
269 divided by 400 is 0 with a remainder of 269.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we take 0 away from 269, we end up with 269.
Fetch the next digit (3) from the dividend, attach it to 269 and continue: 2693 / 400

Going ahead to step 6:
The number 400 fits into 2693 6 times, leaving a remainder of 293.
The number 6 becomes the next digit in our result. 
Result so far: 1706.0
If we take 2400 away from 2693, we end up with 293.
Bring next digit (9) of the dividend behind the 293 and repeat the process: 2939 / 400

Let's proceed to step 7:
400 can be fit into 2939 7 times, resulting in a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 17067.0
The remainder is 139 after subtracting 2800 from 2939.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 400

Going ahead to step 8:
When dividing 1393 by 400, we get 3 with a remainder of 193.
The next digit of our result is 3. 
Result so far: 170673.0
If we take 1200 away from 1393, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
The number 400 fits into 1930 4 times, leaving a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 170673.4
Subtract 1600 from 1930 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
The number 400 fits into 3300 8 times, leaving a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 170673.48
Subtract 3200 from 3300 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
If we divide 1000 by 400, we get 2 and a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 170673.482
Deduct 800 from 1000 and we're left 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.

Step 12:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 170673.4825
Subtract 2000 from 2000 to get 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:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 170673.4825
Deduct 0 from 0 and we're left 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.

Advancing to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 170673.4825
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.

In conclusion, the division gives 170673.4825 with a balance of 0.0.
