We're dividing 4626402 by 81 
We're looking to find how many times 81 goes into 4626402.

Step 1:
When dividing 4 by 81, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 81

Going ahead to step 2:
46 divided by 81 is 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 81

Advancing to step 3:
If we divide 462 by 81, we get 5 and a remainder of 57.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 405 from 462 to get 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 81

Moving on to step 4:
If we divide 576 by 81, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 567 from 576 to get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 81

Going ahead to step 5:
81 can be fit into 94 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 571.0
The remainder is 13 after subtracting 81 from 94.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 81

Moving on to step 6:
If we divide 130 by 81, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 5711.0
Subtracting 81 from 130 leaves us with 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 81

Let's proceed to step 7:
If we divide 492 by 81, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 57116.0
If we subtract 486 from 492, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 57116.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
81 goes into 600 7 times with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 57116.07
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
If we divide 330 by 81, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 57116.074
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
When dividing 60 by 81, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 57116.074
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 57116.07407
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
If we divide 330 by 81, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 57116.074074
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 81 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 57116.074074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
If we divide 600 by 81, we get 7 and a remainder of 33.
The next digit of our result is 7. 
Result so far: 57116.07407407
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 57116.07407407, with a leftover of 3.3e-08.
