3225397 divided by 866 
We're looking to find how many times 866 goes into 3225397.

Advancing to step 1:
3 divided by 866 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 866

Moving on to step 2:
The number 866 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 866

Going ahead to step 3:
866 can be fit into 322 0 times, resulting in a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 322, we end up with 322.
Bring next digit (5) of the dividend behind the 322 and repeat the process: 3225 / 866

Going ahead to step 4:
When dividing 3225 by 866, we get 3 with a remainder of 627.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 627 after subtracting 2598 from 3225.
Take the next digit (3) from the dividend and append it to 627, then repeat: 6273 / 866

On to step 5:
The number 866 fits into 6273 7 times, leaving a remainder of 211.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 6062 from 6273 and we're left with 211.
Fetch the next digit (9) from the dividend, attach it to 211 and continue: 2119 / 866

Going ahead to step 6:
When dividing 2119 by 866, we get 2 with a remainder of 387.
The next digit of our result is 2. 
Result so far: 372.0
The remainder is 387 after subtracting 1732 from 2119.
Grab the next digit (7) from the dividend, add it to 387, then carry on: 3877 / 866

Moving on to step 7:
The number 866 fits into 3877 4 times, leaving a remainder of 413.
Use 4 as the next digit of our solution. 
Result so far: 3724.0
Subtract 3464 from 3877 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 8:
4130 divided by 866 is 4 with a remainder of 666.
Record the quotient 4 as the next digit in the result. 
Result so far: 3724.4
If we take 3464 away from 4130, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 9:
If we divide 6660 by 866, we get 7 and a remainder of 598.
The number 7 becomes the next digit in our result. 
Result so far: 3724.47
If we subtract 6062 from 6660, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
If we divide 5980 by 866, we get 6 and a remainder of 784.
Put 6 as the next digit of the answer. 
Result so far: 3724.476
Deduct 5196 from 5980 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 11:
If we divide 7840 by 866, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 3724.4769
If we take 7794 away from 7840, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
866 can be fit into 460 0 times, resulting in a remainder of 460.
The next digit of our result is 0. 
Result so far: 3724.4769
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 13:
The number 866 fits into 4600 5 times, leaving a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 3724.476905
Subtract 4330 from 4600 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 14:
866 goes into 2700 3 times with a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 3724.4769053
If we take 2598 away from 2700, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 15:
If we divide 1020 by 866, we get 1 and a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 3724.47690531
Subtract 866 from 1020 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Our division results in 3724.47690531 with a remaining 1.54e-07.
