37503480 divided by 866 
We want to figure out the number of times 37503480 can be divided by 866.

On 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
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 866

Let's proceed to step 2:
866 can be fit into 37 0 times, resulting in a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 866

Moving on to step 3:
When dividing 375 by 866, we get 0 with a remainder of 375.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 375 after subtracting 0 from 375.
Fetch the next digit (0) from the dividend, attach it to 375 and continue: 3750 / 866

Let's proceed to step 4:
3750 divided by 866 is 4 with a remainder of 286.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3464 from 3750 and we're left with 286.
Append the next digit (3) from the dividend to 286 and continue with: 2863 / 866

Going ahead to step 5:
2863 divided by 866 is 3 with a remainder of 265.
Write down 3 as next digit of the result. 
Result so far: 43.0
Deduct 2598 from 2863 and we're left with 265.
Bring next digit (4) of the dividend behind the 265 and repeat the process: 2654 / 866

Advancing to step 6:
If we divide 2654 by 866, we get 3 and a remainder of 56.
The next digit of our result is 3. 
Result so far: 433.0
If we take 2598 away from 2654, we end up with 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 866

Let's proceed to step 7:
568 divided by 866 is 0 with a remainder of 568.
The next digit of our result is 0. 
Result so far: 4330.0
The remainder is 568 after subtracting 0 from 568.
Append the next digit (0) from the dividend to 568 and continue with: 5680 / 866

Step 8:
When dividing 5680 by 866, we get 6 with a remainder of 484.
Use 6 as the next digit of our solution. 
Result so far: 43306.0
The remainder is 484 after subtracting 5196 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 9:
When dividing 4840 by 866, we get 5 with a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 43306.5
Subtracting 4330 from 4840 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
5100 divided by 866 is 5 with a remainder of 770.
The next digit of our result is 5. 
Result so far: 43306.55
If we take 4330 away from 5100, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

After the division, we end up with 43306.55 and a remainder of 0.77.
