97555870 ÷ 904 
We're looking to find how many times 904 goes into 97555870.

Step 1:
If we divide 9 by 904, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 904

Step 2:
When dividing 97 by 904, we get 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Bring next digit (5) of the dividend behind the 97 and repeat the process: 975 / 904

Step 3:
904 goes into 975 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 904 away from 975, we end up with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 904

Going ahead to step 4:
When dividing 715 by 904, we get 0 with a remainder of 715.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 715 and we're left with 715.
Include the next digit (5) from the dividend after 715, then repeat: 7155 / 904

Going ahead to step 5:
904 goes into 7155 7 times with a remainder of 827.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 827 after subtracting 6328 from 7155.
Append the next digit (8) from the dividend to 827 and continue with: 8278 / 904

On to step 6:
904 can be fit into 8278 9 times, resulting in a remainder of 142.
The number 9 becomes the next digit in our result. 
Result so far: 1079.0
Deduct 8136 from 8278 and we're left with 142.
Bring next digit (7) of the dividend behind the 142 and repeat the process: 1427 / 904

Moving on to step 7:
1427 divided by 904 is 1 with a remainder of 523.
Use 1 as the next digit of our solution. 
Result so far: 10791.0
Subtract 904 from 1427 to get 523.
Append the next digit (0) from the dividend to 523 and continue with: 5230 / 904

Advancing to step 8:
If we divide 5230 by 904, we get 5 and a remainder of 710.
Use 5 as the next digit of our solution. 
Result so far: 107915.0
Subtracting 4520 from 5230 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 9:
904 goes into 7100 7 times with a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 107915.7
If we subtract 6328 from 7100, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 10:
7720 divided by 904 is 8 with a remainder of 488.
Record the quotient 8 as the next digit in the result. 
Result so far: 107915.78
If we subtract 7232 from 7720, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 11:
The number 904 fits into 4880 5 times, leaving a remainder of 360.
Write down 5 as next digit of the result. 
Result so far: 107915.785
Deduct 4520 from 4880 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
When dividing 3600 by 904, we get 3 with a remainder of 888.
The next digit of our result is 3. 
Result so far: 107915.7853
The remainder is 888 after subtracting 2712 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Let's proceed to step 13:
The number 904 fits into 8880 9 times, leaving a remainder of 744.
The number 9 becomes the next digit in our result. 
Result so far: 107915.78539
If we take 8136 away from 8880, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Moving on to step 14:
When dividing 7440 by 904, we get 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 107915.785398
Deduct 7232 from 7440 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
The number 904 fits into 2080 2 times, leaving a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 107915.7853982
Subtracting 1808 from 2080 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 16:
When dividing 2720 by 904, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 107915.78539823
The remainder is 8 after subtracting 2712 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 107915.78539823 and a remainder of 8e-09.
