83341958 ÷ 81 
Let's see how many times 81 fits into 83341958.

Moving on to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 81

Advancing to step 2:
81 can be fit into 83 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 81 away from 83, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 81

Moving on to step 3:
81 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 81

Moving on to step 4:
81 goes into 234 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 72 after subtracting 162 from 234.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 81

Going ahead to step 5:
721 divided by 81 is 8 with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 1028.0
Deduct 648 from 721 and we're left with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 81

On to step 6:
81 can be fit into 739 9 times, resulting in a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 10289.0
Subtracting 729 from 739 leaves us with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 81

Advancing to step 7:
The number 81 fits into 105 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 102891.0
Subtract 81 from 105 to get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 81

Moving on to step 8:
If we divide 248 by 81, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1028913.0
If we take 243 away from 248, 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.

On to step 9:
50 divided by 81 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1028913.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
500 divided by 81 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 1028913.06
Subtracting 486 from 500 leaves us 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.

Step 11:
The number 81 fits into 140 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 1028913.061
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 12:
81 can be fit into 590 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 1028913.0617
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
If we divide 230 by 81, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 1028913.06172
Deduct 162 from 230 and we're left with 68.
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.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028913.061728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
If we divide 320 by 81, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 1028913.0617283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 16:
If we divide 770 by 81, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 1028913.06172839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The quotient of the division is 1028913.06172839, and the remainder is 4.1e-08.
