We're dividing 5435593 by 400 
We want to figure out the number of times 5435593 can be divided by 400.

Step 1:
If we divide 5 by 400, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 400

Moving on to step 2:
400 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 400

Moving on to step 3:
400 goes into 543 1 times with a remainder of 143.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 400 from 543 and we're left with 143.
Take the next digit (5) from the dividend and append it to 143, then repeat: 1435 / 400

Going ahead to step 4:
400 can be fit into 1435 3 times, resulting in a remainder of 235.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1200 from 1435 and we're left with 235.
Grab the next digit (5) from the dividend, add it to 235, then carry on: 2355 / 400

Let's proceed to step 5:
When dividing 2355 by 400, we get 5 with a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
The remainder is 355 after subtracting 2000 from 2355.
Bring next digit (9) of the dividend behind the 355 and repeat the process: 3559 / 400

Advancing to step 6:
3559 divided by 400 is 8 with a remainder of 359.
The number 8 becomes the next digit in our result. 
Result so far: 1358.0
Subtract 3200 from 3559 to get 359.
Bring next digit (3) of the dividend behind the 359 and repeat the process: 3593 / 400

Moving on to step 7:
400 can be fit into 3593 8 times, resulting in a remainder of 393.
Record the quotient 8 as the next digit in the result. 
Result so far: 13588.0
If we subtract 3200 from 3593, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Let's proceed to step 8:
If we divide 3930 by 400, we get 9 and a remainder of 330.
Use 9 as the next digit of our solution. 
Result so far: 13588.9
Subtract 3600 from 3930 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.

Moving on to step 9:
400 goes into 3300 8 times with a remainder of 100.
The next digit of our result is 8. 
Result so far: 13588.98
Subtracting 3200 from 3300 leaves us 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 10:
If we divide 1000 by 400, we get 2 and a remainder of 200.
The next digit of our result is 2. 
Result so far: 13588.982
If we take 800 away from 1000, 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.

Going ahead to step 11:
If we divide 2000 by 400, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13588.9825
Deduct 2000 from 2000 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.

Going ahead to step 12:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13588.9825
Subtract 0 from 0 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.

Moving on to step 13:
400 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13588.9825
Subtract 0 from 0 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.

The quotient of the division is 13588.9825, and the remainder is 0.0.
