Let's divide 81641101 by 89
Let's see how many times 89 fits into 81641101.

On to step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 89

Advancing to step 2:
The number 89 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 89

On to step 3:
When dividing 816 by 89, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 801 from 816 to get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 89

Advancing to step 4:
154 divided by 89 is 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we take 89 away from 154, we end up with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 89

Going ahead to step 5:
If we divide 651 by 89, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 917.0
If we subtract 623 from 651, we get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 89

Advancing to step 6:
If we divide 281 by 89, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 9173.0
Subtract 267 from 281 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 89

On to step 7:
The number 89 fits into 140 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 91731.0
If we subtract 89 from 140, we get 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 89

On to step 8:
When dividing 511 by 89, we get 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 917315.0
Deduct 445 from 511 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
89 goes into 660 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 917315.7
Subtract 623 from 660 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
89 goes into 370 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 917315.74
The remainder is 14 after subtracting 356 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
89 can be fit into 140 1 times, resulting in a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 917315.741
The remainder is 51 after subtracting 89 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
When dividing 510 by 89, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 917315.7415
Subtract 445 from 510 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
89 goes into 650 7 times with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 917315.74157
If we subtract 623 from 650, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
89 goes into 270 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 917315.741573
If we take 267 away from 270, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 15:
30 divided by 89 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 917315.741573
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 16:
300 divided by 89 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 917315.74157303
The remainder is 33 after subtracting 267 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 917315.74157303, with a leftover of 3.3e-08.
