We divide 617690 by 81
Our goal is to divide 617690 by 81.

Advancing to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 81

Advancing to step 2:
81 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 81

On to step 3:
81 can be fit into 617 7 times, resulting in a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 567 from 617 and we're left with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 81

Advancing to step 4:
The number 81 fits into 506 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 486 from 506 leaves us with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 81

On to step 5:
209 divided by 81 is 2 with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 762.0
Subtract 162 from 209 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 81

Advancing to step 6:
81 goes into 470 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7625.0
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 7625.8
If we take 648 away from 650, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 81 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7625.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 7625.802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
When dividing 380 by 81, we get 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 7625.8024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 81 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 7625.80246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
740 divided by 81 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 7625.802469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
81 can be fit into 110 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 7625.8024691
Deduct 81 from 110 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
When dividing 290 by 81, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 7625.80246913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 7625.80246913 with a remaining 4.7e-08.
