We're dividing 80907561 by 951 
We're looking to find how many times 951 goes into 80907561.

Going ahead to step 1:
8 divided by 951 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 951

Advancing to step 2:
If we divide 80 by 951, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 951

Moving on to step 3:
951 goes into 809 0 times with a remainder of 809.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Bring next digit (0) of the dividend behind the 809 and repeat the process: 8090 / 951

Moving on to step 4:
If we divide 8090 by 951, we get 8 and a remainder of 482.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7608 from 8090 and we're left with 482.
Append the next digit (7) from the dividend to 482 and continue with: 4827 / 951

Step 5:
When dividing 4827 by 951, we get 5 with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 4755 from 4827, we get 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 951

Moving on to step 6:
725 divided by 951 is 0 with a remainder of 725.
Put 0 as the next digit of the answer. 
Result so far: 850.0
Deduct 0 from 725 and we're left with 725.
Fetch the next digit (6) from the dividend, attach it to 725 and continue: 7256 / 951

On to step 7:
951 goes into 7256 7 times with a remainder of 599.
Record the quotient 7 as the next digit in the result. 
Result so far: 8507.0
Subtracting 6657 from 7256 leaves us with 599.
Fetch the next digit (1) from the dividend, attach it to 599 and continue: 5991 / 951

Moving on to step 8:
When dividing 5991 by 951, we get 6 with a remainder of 285.
Record the quotient 6 as the next digit in the result. 
Result so far: 85076.0
Deduct 5706 from 5991 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 9:
951 goes into 2850 2 times with a remainder of 948.
Record the quotient 2 as the next digit in the result. 
Result so far: 85076.2
Subtract 1902 from 2850 to get 948.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9480, and continue the process.

Let's proceed to step 10:
951 can be fit into 9480 9 times, resulting in a remainder of 921.
The next digit of our result is 9. 
Result so far: 85076.29
Subtracting 8559 from 9480 leaves us with 921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9210, and continue the process.

Step 11:
When dividing 9210 by 951, we get 9 with a remainder of 651.
Put 9 as the next digit of the answer. 
Result so far: 85076.299
Deduct 8559 from 9210 and we're left with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

The quotient of the division is 85076.299, and the remainder is 0.0651.
