81856795 ÷ 661 
We're looking to find how many times 661 goes into 81856795.

Moving on to step 1:
When dividing 8 by 661, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 661

Advancing to step 2:
81 divided by 661 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 661

On to step 3:
When dividing 818 by 661, we get 1 with a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 661 away from 818, we end up with 157.
Fetch the next digit (5) from the dividend, attach it to 157 and continue: 1575 / 661

On to step 4:
The number 661 fits into 1575 2 times, leaving a remainder of 253.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1322 away from 1575, we end up with 253.
Bring next digit (6) of the dividend behind the 253 and repeat the process: 2536 / 661

Step 5:
When dividing 2536 by 661, we get 3 with a remainder of 553.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 1983 from 2536, we get 553.
Grab the next digit (7) from the dividend, add it to 553, then carry on: 5537 / 661

Let's proceed to step 6:
661 can be fit into 5537 8 times, resulting in a remainder of 249.
Record the quotient 8 as the next digit in the result. 
Result so far: 1238.0
If we subtract 5288 from 5537, we get 249.
Take the next digit (9) from the dividend and append it to 249, then repeat: 2499 / 661

Moving on to step 7:
2499 divided by 661 is 3 with a remainder of 516.
Use 3 as the next digit of our solution. 
Result so far: 12383.0
Deduct 1983 from 2499 and we're left with 516.
Include the next digit (5) from the dividend after 516, then repeat: 5165 / 661

Moving on to step 8:
661 goes into 5165 7 times with a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 123837.0
Subtracting 4627 from 5165 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 9:
The number 661 fits into 5380 8 times, leaving a remainder of 92.
The next digit of our result is 8. 
Result so far: 123837.8
Subtracting 5288 from 5380 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 10:
If we divide 920 by 661, we get 1 and a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 123837.81
Deduct 661 from 920 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 11:
The number 661 fits into 2590 3 times, leaving a remainder of 607.
Use 3 as the next digit of our solution. 
Result so far: 123837.813
Subtracting 1983 from 2590 leaves us with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Advancing to step 12:
6070 divided by 661 is 9 with a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 123837.8139
The remainder is 121 after subtracting 5949 from 6070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 13:
If we divide 1210 by 661, we get 1 and a remainder of 549.
Write down 1 as next digit of the result. 
Result so far: 123837.81391
Deduct 661 from 1210 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Moving on to step 14:
When dividing 5490 by 661, we get 8 with a remainder of 202.
Write down 8 as next digit of the result. 
Result so far: 123837.813918
Subtract 5288 from 5490 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 15:
The number 661 fits into 2020 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 123837.8139183
Subtracting 1983 from 2020 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 16:
661 goes into 370 0 times with a remainder of 370.
The next digit of our result is 0. 
Result so far: 123837.8139183
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 123837.8139183, with a leftover of 3.7e-07.
