91220376 ÷ 400 
We're looking to find how many times 400 goes into 91220376.

Advancing to step 1:
400 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 400

Step 2:
The number 400 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 400

Step 3:
400 goes into 912 2 times with a remainder of 112.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 112 after subtracting 800 from 912.
Fetch the next digit (2) from the dividend, attach it to 112 and continue: 1122 / 400

Going ahead to step 4:
1122 divided by 400 is 2 with a remainder of 322.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 800 from 1122 leaves us with 322.
Bring next digit (0) of the dividend behind the 322 and repeat the process: 3220 / 400

Advancing to step 5:
When dividing 3220 by 400, we get 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
The remainder is 20 after subtracting 3200 from 3220.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 400

Let's proceed to step 6:
When dividing 203 by 400, we get 0 with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 2280.0
If we subtract 0 from 203, we get 203.
Take the next digit (7) from the dividend and append it to 203, then repeat: 2037 / 400

Step 7:
If we divide 2037 by 400, we get 5 and a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 22805.0
Subtracting 2000 from 2037 leaves us with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 400

Moving on to step 8:
When dividing 376 by 400, we get 0 with a remainder of 376.
Put 0 as the next digit of the answer. 
Result so far: 228050.0
The remainder is 376 after subtracting 0 from 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 9:
The number 400 fits into 3760 9 times, leaving a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 228050.9
Subtracting 3600 from 3760 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
400 goes into 1600 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 228050.94
The remainder is 0 after subtracting 1600 from 1600.
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 11:
The number 400 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 228050.94
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.

Let's proceed to step 12:
0 divided by 400 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 228050.94
The remainder is 0 after subtracting 0 from 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 228050.94 with a remaining 0.0.
