97600891 ÷ 438 
We want to divide 97600891 by 438.

Step 1:
If we divide 9 by 438, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 438

Going ahead to step 2:
97 divided by 438 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 438

On to step 3:
The number 438 fits into 976 2 times, leaving a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 876 from 976 and we're left with 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 438

Let's proceed to step 4:
438 goes into 1000 2 times with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 876 away from 1000, we end up with 124.
Grab the next digit (0) from the dividend, add it to 124, then carry on: 1240 / 438

Moving on to step 5:
438 can be fit into 1240 2 times, resulting in a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Deduct 876 from 1240 and we're left with 364.
Take the next digit (8) from the dividend and append it to 364, then repeat: 3648 / 438

Moving on to step 6:
If we divide 3648 by 438, we get 8 and a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 2228.0
If we subtract 3504 from 3648, we get 144.
Include the next digit (9) from the dividend after 144, then repeat: 1449 / 438

Going ahead to step 7:
438 goes into 1449 3 times with a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 22283.0
If we take 1314 away from 1449, we end up with 135.
Append the next digit (1) from the dividend to 135 and continue with: 1351 / 438

Going ahead to step 8:
438 can be fit into 1351 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 222833.0
Subtracting 1314 from 1351 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
438 can be fit into 370 0 times, resulting in a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 222833.0
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
438 can be fit into 3700 8 times, resulting in a remainder of 196.
The next digit of our result is 8. 
Result so far: 222833.08
Subtract 3504 from 3700 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
When dividing 1960 by 438, we get 4 with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 222833.084
Subtract 1752 from 1960 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
If we divide 2080 by 438, we get 4 and a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 222833.0844
If we take 1752 away from 2080, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final result is 222833.0844 with a remainder of 0.00328.
