38435143 ÷ 400 
We want to figure out the number of times 38435143 can be divided by 400.

Advancing to step 1:
400 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 400

Advancing to step 2:
400 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 400

On to step 3:
If we divide 384 by 400, we get 0 and a remainder of 384.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 384 leaves us with 384.
Include the next digit (3) from the dividend after 384, then repeat: 3843 / 400

Step 4:
If we divide 3843 by 400, we get 9 and a remainder of 243.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 3600 from 3843 and we're left with 243.
Include the next digit (5) from the dividend after 243, then repeat: 2435 / 400

Let's proceed to step 5:
When dividing 2435 by 400, we get 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 2400 from 2435, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 400

Going ahead to step 6:
The number 400 fits into 351 0 times, leaving a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 960.0
Subtract 0 from 351 to get 351.
Append the next digit (4) from the dividend to 351 and continue with: 3514 / 400

Going ahead to step 7:
When dividing 3514 by 400, we get 8 with a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 9608.0
If we subtract 3200 from 3514, we get 314.
Include the next digit (3) from the dividend after 314, then repeat: 3143 / 400

On to step 8:
The number 400 fits into 3143 7 times, leaving a remainder of 343.
Put 7 as the next digit of the answer. 
Result so far: 96087.0
The remainder is 343 after subtracting 2800 from 3143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 9:
3430 divided by 400 is 8 with a remainder of 230.
The next digit of our result is 8. 
Result so far: 96087.8
Deduct 3200 from 3430 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
400 can be fit into 2300 5 times, resulting in a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 96087.85
If we subtract 2000 from 2300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Record the quotient 7 as the next digit in the result. 
Result so far: 96087.857
If we take 2800 away from 3000, we end up 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.

Moving on to step 12:
The number 400 fits into 2000 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 96087.8575
If we take 2000 away from 2000, 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.

Advancing to step 13:
400 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 96087.8575
If we subtract 0 from 0, we 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.

Advancing to step 14:
400 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 96087.8575
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.

Our division results in 96087.8575 with a remaining 0.0.
