We look at the division of 81935489 by 651 
We want to divide 81935489 by 651.

Let's proceed to step 1:
If we divide 8 by 651, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 651

Going ahead to step 2:
81 divided by 651 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 651

Let's proceed to step 3:
651 goes into 819 1 times with a remainder of 168.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 651 away from 819, we end up with 168.
Grab the next digit (3) from the dividend, add it to 168, then carry on: 1683 / 651

Advancing to step 4:
When dividing 1683 by 651, we get 2 with a remainder of 381.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1302 away from 1683, we end up with 381.
Take the next digit (5) from the dividend and append it to 381, then repeat: 3815 / 651

On to step 5:
When dividing 3815 by 651, we get 5 with a remainder of 560.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 560 after subtracting 3255 from 3815.
Include the next digit (4) from the dividend after 560, then repeat: 5604 / 651

Advancing to step 6:
651 goes into 5604 8 times with a remainder of 396.
The next digit of our result is 8. 
Result so far: 1258.0
Deduct 5208 from 5604 and we're left with 396.
Take the next digit (8) from the dividend and append it to 396, then repeat: 3968 / 651

Moving on to step 7:
If we divide 3968 by 651, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 12586.0
Subtracting 3906 from 3968 leaves us with 62.
Take the next digit (9) from the dividend and append it to 62, then repeat: 629 / 651

Step 8:
The number 651 fits into 629 0 times, leaving a remainder of 629.
The number 0 becomes the next digit in our result. 
Result so far: 125860.0
If we take 0 away from 629, we end up with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

On to step 9:
651 can be fit into 6290 9 times, resulting in a remainder of 431.
The next digit of our result is 9. 
Result so far: 125860.9
Subtracting 5859 from 6290 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 10:
If we divide 4310 by 651, we get 6 and a remainder of 404.
The next digit of our result is 6. 
Result so far: 125860.96
The remainder is 404 after subtracting 3906 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 11:
651 goes into 4040 6 times with a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 125860.966
Subtract 3906 from 4040 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

In conclusion, the division gives 125860.966 with a balance of 0.0134.
