We look at the division of 400633 by 91 
We're looking to find how many times 91 goes into 400633.

Advancing to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 91

Going ahead to step 2:
91 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 91

Going ahead to step 3:
91 goes into 400 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 364 from 400 leaves us with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 91

Moving on to step 4:
If we divide 366 by 91, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 364 from 366 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 91

On to step 5:
When dividing 23 by 91, we get 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 440.0
If we take 0 away from 23, we end up with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 91

Advancing to step 6:
91 can be fit into 233 2 times, resulting in a remainder of 51.
The next digit of our result is 2. 
Result so far: 4402.0
The remainder is 51 after subtracting 182 from 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 4402.5
If we subtract 455 from 510, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
550 divided by 91 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4402.56
Subtracting 546 from 550 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
If we divide 40 by 91, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 4402.56
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
The number 91 fits into 400 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4402.5604
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
When dividing 360 by 91, we get 3 with a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 4402.56043
If we take 273 away from 360, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 12:
91 can be fit into 870 9 times, resulting in a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 4402.560439
If we take 819 away from 870, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 13:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4402.5604395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 14:
91 goes into 550 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4402.56043956
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 4402.56043956 with a balance of 4e-09.
