We divide 97315854 by 90
We want to figure out the number of times 97315854 can be divided by 90.

Going ahead to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 90

Moving on to step 2:
If we divide 97 by 90, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 90 away from 97, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 90

Moving on to step 3:
If we divide 73 by 90, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 90

Let's proceed to step 4:
731 divided by 90 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 720 from 731 and we're left with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 90

Let's proceed to step 5:
90 can be fit into 115 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1081.0
Subtract 90 from 115 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 90

Step 6:
When dividing 258 by 90, we get 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 10812.0
The remainder is 78 after subtracting 180 from 258.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 90

Step 7:
90 can be fit into 785 8 times, resulting in a remainder of 65.
The number 8 becomes the next digit in our result. 
Result so far: 108128.0
If we subtract 720 from 785, we get 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 90

Step 8:
The number 90 fits into 654 7 times, leaving a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 1081287.0
Subtracting 630 from 654 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 90, we get 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1081287.2
Deduct 180 from 240 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 90, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1081287.26
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 90, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 1081287.266
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 1081287.266 and a remainder of 0.006.
