Let's divide 81704590 by 124
We want to divide 81704590 by 124.

Going ahead to step 1:
124 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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 / 124

Going ahead to step 2:
124 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 124

Let's proceed to step 3:
If we divide 817 by 124, we get 6 and a remainder of 73.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 744 from 817 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 124

Step 4:
If we divide 730 by 124, we get 5 and a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtract 620 from 730 to get 110.
Append the next digit (4) from the dividend to 110 and continue with: 1104 / 124

Advancing to step 5:
When dividing 1104 by 124, we get 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 658.0
If we take 992 away from 1104, we end up with 112.
Take the next digit (5) from the dividend and append it to 112, then repeat: 1125 / 124

Going ahead to step 6:
If we divide 1125 by 124, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 6589.0
If we take 1116 away from 1125, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 124

Step 7:
When dividing 99 by 124, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 65890.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (0) from the dividend, add it to 99, then carry on: 990 / 124

Moving on to step 8:
The number 124 fits into 990 7 times, leaving a remainder of 122.
Use 7 as the next digit of our solution. 
Result so far: 658907.0
If we subtract 868 from 990, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 9:
If we divide 1220 by 124, we get 9 and a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 658907.9
If we take 1116 away from 1220, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
The number 124 fits into 1040 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 658907.98
The remainder is 48 after subtracting 992 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
124 can be fit into 480 3 times, resulting in a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 658907.983
Subtract 372 from 480 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
1080 divided by 124 is 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 658907.9838
If we subtract 992 from 1080, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 13:
124 can be fit into 880 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 658907.98387
Deduct 868 from 880 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
When dividing 120 by 124, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 658907.98387
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
124 can be fit into 1200 9 times, resulting in a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 658907.9838709
Subtract 1116 from 1200 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 16:
The number 124 fits into 840 6 times, leaving a remainder of 96.
The next digit of our result is 6. 
Result so far: 658907.98387096
Subtracting 744 from 840 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 658907.98387096 and a remainder of 9.6e-08.
