8576381 ÷ 861 
Our goal is to divide 8576381 by 861.

Going ahead to step 1:
The number 861 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 861

Moving on to step 2:
If we divide 85 by 861, we get 0 and a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 861

On to step 3:
When dividing 857 by 861, we get 0 with a remainder of 857.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 857, we end up with 857.
Grab the next digit (6) from the dividend, add it to 857, then carry on: 8576 / 861

Step 4:
861 goes into 8576 9 times with a remainder of 827.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7749 from 8576, we get 827.
Include the next digit (3) from the dividend after 827, then repeat: 8273 / 861

Going ahead to step 5:
861 goes into 8273 9 times with a remainder of 524.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Subtracting 7749 from 8273 leaves us with 524.
Fetch the next digit (8) from the dividend, attach it to 524 and continue: 5248 / 861

Step 6:
If we divide 5248 by 861, we get 6 and a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 996.0
The remainder is 82 after subtracting 5166 from 5248.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 861

Step 7:
When dividing 821 by 861, we get 0 with a remainder of 821.
The number 0 becomes the next digit in our result. 
Result so far: 9960.0
Subtract 0 from 821 to get 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Let's proceed to step 8:
If we divide 8210 by 861, we get 9 and a remainder of 461.
Use 9 as the next digit of our solution. 
Result so far: 9960.9
If we take 7749 away from 8210, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Moving on to step 9:
When dividing 4610 by 861, we get 5 with a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 9960.95
Deduct 4305 from 4610 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 10:
When dividing 3050 by 861, we get 3 with a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 9960.953
The remainder is 467 after subtracting 2583 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

On to step 11:
The number 861 fits into 4670 5 times, leaving a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 9960.9535
Subtracting 4305 from 4670 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 12:
When dividing 3650 by 861, we get 4 with a remainder of 206.
Use 4 as the next digit of our solution. 
Result so far: 9960.95354
The remainder is 206 after subtracting 3444 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 13:
When dividing 2060 by 861, we get 2 with a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 9960.953542
Deduct 1722 from 2060 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 14:
When dividing 3380 by 861, we get 3 with a remainder of 797.
Put 3 as the next digit of the answer. 
Result so far: 9960.9535423
Deduct 2583 from 3380 and we're left with 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Let's proceed to step 15:
If we divide 7970 by 861, we get 9 and a remainder of 221.
Record the quotient 9 as the next digit in the result. 
Result so far: 9960.95354239
Subtracting 7749 from 7970 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

After the division, we end up with 9960.95354239 and a remainder of 2.21e-07.
