We look at the division of 3643397 by 775 
We want to figure out the number of times 3643397 can be divided by 775.

Let's proceed to step 1:
775 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 775

Let's proceed to step 2:
775 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 775

Advancing to step 3:
775 can be fit into 364 0 times, resulting in a remainder of 364.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 364 and we're left with 364.
Take the next digit (3) from the dividend and append it to 364, then repeat: 3643 / 775

Moving on to step 4:
3643 divided by 775 is 4 with a remainder of 543.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 3100 from 3643, we get 543.
Grab the next digit (3) from the dividend, add it to 543, then carry on: 5433 / 775

Let's proceed to step 5:
When dividing 5433 by 775, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 47.0
Subtracting 5425 from 5433 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 775

On to step 6:
If we divide 89 by 775, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
The remainder is 89 after subtracting 0 from 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 775

On to step 7:
If we divide 897 by 775, we get 1 and a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 4701.0
If we take 775 away from 897, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 8:
775 goes into 1220 1 times with a remainder of 445.
Write down 1 as next digit of the result. 
Result so far: 4701.1
The remainder is 445 after subtracting 775 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 9:
775 can be fit into 4450 5 times, resulting in a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 4701.15
If we take 3875 away from 4450, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 10:
5750 divided by 775 is 7 with a remainder of 325.
Use 7 as the next digit of our solution. 
Result so far: 4701.157
Subtract 5425 from 5750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 11:
If we divide 3250 by 775, we get 4 and a remainder of 150.
The number 4 becomes the next digit in our result. 
Result so far: 4701.1574
If we subtract 3100 from 3250, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
775 goes into 1500 1 times with a remainder of 725.
The number 1 becomes the next digit in our result. 
Result so far: 4701.15741
Subtracting 775 from 1500 leaves us with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 13:
775 goes into 7250 9 times with a remainder of 275.
The next digit of our result is 9. 
Result so far: 4701.157419
Subtract 6975 from 7250 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 14:
If we divide 2750 by 775, we get 3 and a remainder of 425.
Write down 3 as next digit of the result. 
Result so far: 4701.1574193
Subtracting 2325 from 2750 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 15:
When dividing 4250 by 775, we get 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 4701.15741935
Subtract 3875 from 4250 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final result is 4701.15741935 with a remainder of 3.75e-07.
