We divide 64360997 by 400
Our goal is to divide 64360997 by 400.

Step 1:
400 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 400

Step 2:
400 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 400

Moving on to step 3:
If we divide 643 by 400, we get 1 and a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 243 after subtracting 400 from 643.
Append the next digit (6) from the dividend to 243 and continue with: 2436 / 400

Moving on to step 4:
If we divide 2436 by 400, we get 6 and a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 36 after subtracting 2400 from 2436.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 400

On to step 5:
If we divide 360 by 400, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 160.0
Subtracting 0 from 360 leaves us with 360.
Bring next digit (9) of the dividend behind the 360 and repeat the process: 3609 / 400

Going ahead to step 6:
When dividing 3609 by 400, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1609.0
The remainder is 9 after subtracting 3600 from 3609.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 400

Advancing to step 7:
The number 400 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 16090.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 400

On to step 8:
400 goes into 997 2 times with a remainder of 197.
Put 2 as the next digit of the answer. 
Result so far: 160902.0
Subtracting 800 from 997 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 9:
400 can be fit into 1970 4 times, resulting in a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 160902.4
If we take 1600 away from 1970, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
If we divide 3700 by 400, we get 9 and a remainder of 100.
The next digit of our result is 9. 
Result so far: 160902.49
If we take 3600 away from 3700, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to 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: 160902.492
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.

Going ahead to step 12:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 160902.4925
If we subtract 2000 from 2000, 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 13:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 160902.4925
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.

Let's proceed to step 14:
400 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 160902.4925
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 result is 160902.4925 with a remainder of 0.0.
