90993519 divided by 400 
Our goal is to divide 90993519 by 400.

Step 1:
400 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 400

Going ahead to step 2:
90 divided by 400 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 400

Step 3:
If we divide 909 by 400, we get 2 and a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 800 away from 909, we end up with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 400

On to step 4:
400 goes into 1099 2 times with a remainder of 299.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 800 from 1099 leaves us with 299.
Grab the next digit (3) from the dividend, add it to 299, then carry on: 2993 / 400

Advancing to step 5:
2993 divided by 400 is 7 with a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 227.0
The remainder is 193 after subtracting 2800 from 2993.
Take the next digit (5) from the dividend and append it to 193, then repeat: 1935 / 400

Advancing to step 6:
When dividing 1935 by 400, we get 4 with a remainder of 335.
Put 4 as the next digit of the answer. 
Result so far: 2274.0
If we take 1600 away from 1935, we end up with 335.
Take the next digit (1) from the dividend and append it to 335, then repeat: 3351 / 400

Step 7:
The number 400 fits into 3351 8 times, leaving a remainder of 151.
Record the quotient 8 as the next digit in the result. 
Result so far: 22748.0
Deduct 3200 from 3351 and we're left with 151.
Bring next digit (9) of the dividend behind the 151 and repeat the process: 1519 / 400

Going ahead to step 8:
400 can be fit into 1519 3 times, resulting in a remainder of 319.
The next digit of our result is 3. 
Result so far: 227483.0
Subtracting 1200 from 1519 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
If we divide 3190 by 400, we get 7 and a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 227483.7
Subtracting 2800 from 3190 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
400 can be fit into 3900 9 times, resulting in a remainder of 300.
Put 9 as the next digit of the answer. 
Result so far: 227483.79
The remainder is 300 after subtracting 3600 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 227483.797
If we subtract 2800 from 3000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing 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: 227483.7975
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:
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: 227483.7975
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.

Going ahead to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 227483.7975
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.

Our division results in 227483.7975 with a remaining 0.0.
