We divide 73312122 by 400
We're looking to find how many times 400 goes into 73312122.

On to step 1:
400 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 400

Going ahead to step 2:
400 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 400

Advancing to step 3:
400 can be fit into 733 1 times, resulting in a remainder of 333.
The next digit of our result is 1. 
Result so far: 1.0
If we take 400 away from 733, we end up with 333.
Include the next digit (1) from the dividend after 333, then repeat: 3331 / 400

Let's proceed to step 4:
If we divide 3331 by 400, we get 8 and a remainder of 131.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 3200 from 3331, we get 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 400

Step 5:
400 can be fit into 1312 3 times, resulting in a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
If we subtract 1200 from 1312, we get 112.
Fetch the next digit (1) from the dividend, attach it to 112 and continue: 1121 / 400

Let's proceed to step 6:
400 can be fit into 1121 2 times, resulting in a remainder of 321.
The next digit of our result is 2. 
Result so far: 1832.0
If we subtract 800 from 1121, we get 321.
Take the next digit (2) from the dividend and append it to 321, then repeat: 3212 / 400

Moving on to step 7:
400 goes into 3212 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 18328.0
The remainder is 12 after subtracting 3200 from 3212.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 400

Let's proceed to step 8:
If we divide 122 by 400, we get 0 and a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 183280.0
Subtracting 0 from 122 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 9:
When dividing 1220 by 400, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 183280.3
Subtract 1200 from 1220 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
When dividing 200 by 400, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 183280.3
Deduct 0 from 200 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.

Advancing to step 11:
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: 183280.305
The remainder is 0 after subtracting 2000 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
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: 183280.305
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 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: 183280.305
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.

In conclusion, the division gives 183280.305 with a balance of 0.0.
