We divide 90093122 by 81
We want to figure out the number of times 90093122 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 81

Step 2:
90 divided by 81 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 90, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 81

Moving on to step 3:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 81 away from 90, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 81

Moving on to step 4:
81 goes into 99 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 111.0
Subtracting 81 from 99 leaves us with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 81

Going ahead to step 5:
The number 81 fits into 183 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 1112.0
If we take 162 away from 183, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 81

Moving on to step 6:
81 can be fit into 211 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 11122.0
Subtracting 162 from 211 leaves us with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 81

On to step 7:
If we divide 492 by 81, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 111226.0
The remainder is 6 after subtracting 486 from 492.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 81

Let's proceed to step 8:
81 can be fit into 62 0 times, resulting in a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 1112260.0
Deduct 0 from 62 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
If we divide 620 by 81, we get 7 and a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 1112260.7
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 10:
530 divided by 81 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 1112260.76
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 81 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1112260.765
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
350 divided by 81 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 1112260.7654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
If we divide 260 by 81, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 1112260.76543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1112260.765432
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
When dividing 80 by 81, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1112260.765432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
If we divide 800 by 81, we get 9 and a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 1112260.76543209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 1112260.76543209 with a balance of 7.1e-08.
