81649090 divided by 942 
Our goal is to divide 81649090 by 942.

Step 1:
If we divide 8 by 942, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 942

Step 2:
942 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 942

Moving on to step 3:
942 goes into 816 0 times with a remainder of 816.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 816, we end up with 816.
Fetch the next digit (4) from the dividend, attach it to 816 and continue: 8164 / 942

Moving on to step 4:
942 goes into 8164 8 times with a remainder of 628.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7536 from 8164 leaves us with 628.
Include the next digit (9) from the dividend after 628, then repeat: 6289 / 942

Step 5:
942 can be fit into 6289 6 times, resulting in a remainder of 637.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 5652 from 6289 and we're left with 637.
Take the next digit (0) from the dividend and append it to 637, then repeat: 6370 / 942

On to step 6:
If we divide 6370 by 942, we get 6 and a remainder of 718.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
If we subtract 5652 from 6370, we get 718.
Take the next digit (9) from the dividend and append it to 718, then repeat: 7189 / 942

On to step 7:
7189 divided by 942 is 7 with a remainder of 595.
Record the quotient 7 as the next digit in the result. 
Result so far: 8667.0
If we take 6594 away from 7189, we end up with 595.
Append the next digit (0) from the dividend to 595 and continue with: 5950 / 942

On to step 8:
The number 942 fits into 5950 6 times, leaving a remainder of 298.
Put 6 as the next digit of the answer. 
Result so far: 86676.0
Subtracting 5652 from 5950 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 9:
If we divide 2980 by 942, we get 3 and a remainder of 154.
Record the quotient 3 as the next digit in the result. 
Result so far: 86676.3
If we take 2826 away from 2980, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
1540 divided by 942 is 1 with a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 86676.31
The remainder is 598 after subtracting 942 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 11:
942 can be fit into 5980 6 times, resulting in a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 86676.316
Subtracting 5652 from 5980 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 12:
When dividing 3280 by 942, we get 3 with a remainder of 454.
Record the quotient 3 as the next digit in the result. 
Result so far: 86676.3163
Subtracting 2826 from 3280 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 13:
4540 divided by 942 is 4 with a remainder of 772.
Use 4 as the next digit of our solution. 
Result so far: 86676.31634
Subtract 3768 from 4540 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 14:
942 goes into 7720 8 times with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 86676.316348
If we subtract 7536 from 7720, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 15:
942 can be fit into 1840 1 times, resulting in a remainder of 898.
The number 1 becomes the next digit in our result. 
Result so far: 86676.3163481
If we subtract 942 from 1840, we get 898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

Going ahead to step 16:
The number 942 fits into 8980 9 times, leaving a remainder of 502.
Put 9 as the next digit of the answer. 
Result so far: 86676.31634819
Subtracting 8478 from 8980 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The final result is 86676.31634819 with a remainder of 5.02e-07.
