75770367 ÷ 866 
We want to divide 75770367 by 866.

Going ahead to step 1:
866 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 866

Step 2:
866 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Fetch the next digit (7) from the dividend, attach it to 75 and continue: 757 / 866

Moving on to step 3:
When dividing 757 by 866, we get 0 with a remainder of 757.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 757 to get 757.
Append the next digit (7) from the dividend to 757 and continue with: 7577 / 866

Going ahead to step 4:
7577 divided by 866 is 8 with a remainder of 649.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6928 away from 7577, we end up with 649.
Take the next digit (0) from the dividend and append it to 649, then repeat: 6490 / 866

Moving on to step 5:
866 goes into 6490 7 times with a remainder of 428.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 6062 from 6490, we get 428.
Bring next digit (3) of the dividend behind the 428 and repeat the process: 4283 / 866

Let's proceed to step 6:
4283 divided by 866 is 4 with a remainder of 819.
Use 4 as the next digit of our solution. 
Result so far: 874.0
Subtracting 3464 from 4283 leaves us with 819.
Include the next digit (6) from the dividend after 819, then repeat: 8196 / 866

Advancing to step 7:
866 goes into 8196 9 times with a remainder of 402.
Use 9 as the next digit of our solution. 
Result so far: 8749.0
The remainder is 402 after subtracting 7794 from 8196.
Bring next digit (7) of the dividend behind the 402 and repeat the process: 4027 / 866

On to step 8:
866 can be fit into 4027 4 times, resulting in a remainder of 563.
Put 4 as the next digit of the answer. 
Result so far: 87494.0
If we take 3464 away from 4027, we end up with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Advancing to step 9:
When dividing 5630 by 866, we get 6 with a remainder of 434.
The next digit of our result is 6. 
Result so far: 87494.6
If we subtract 5196 from 5630, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 10:
If we divide 4340 by 866, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 87494.65
Subtracting 4330 from 4340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
The number 866 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 87494.65
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
If we divide 1000 by 866, we get 1 and a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 87494.6501
The remainder is 134 after subtracting 866 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 13:
If we divide 1340 by 866, we get 1 and a remainder of 474.
Use 1 as the next digit of our solution. 
Result so far: 87494.65011
Subtract 866 from 1340 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Our division results in 87494.65011 with a remaining 0.000474.
