Let's divide 100598 by 81
We want to figure out the number of times 100598 can be divided by 81.

Step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 81

On to step 2:
The number 81 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 81

Let's proceed to step 3:
100 divided by 81 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 19 after subtracting 81 from 100.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 81

Let's proceed to step 4:
195 divided by 81 is 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 162 from 195, we get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 81

Advancing to step 5:
81 goes into 339 4 times with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 324 from 339 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 81

Step 6:
158 divided by 81 is 1 with a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1241.0
Subtract 81 from 158 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 1241.9
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
If we divide 410 by 81, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 1241.95
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 81, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 1241.95
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 81 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1241.9506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
81 goes into 140 1 times with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 1241.95061
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
If we divide 590 by 81, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1241.950617
Deduct 567 from 590 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
81 goes into 230 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 1241.9506172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
If we divide 680 by 81, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 1241.95061728
If we subtract 648 from 680, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 1241.95061728 and a remainder of 3.2e-08.
