We're dividing 37903838 by 645 
We're looking to find how many times 645 goes into 37903838.

Moving on to step 1:
3 divided by 645 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 645

Advancing to step 2:
645 goes into 37 0 times with 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.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 645

Moving on to step 3:
645 can be fit into 379 0 times, resulting in a remainder of 379.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Append the next digit (0) from the dividend to 379 and continue with: 3790 / 645

Step 4:
645 can be fit into 3790 5 times, resulting in a remainder of 565.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3225 from 3790 to get 565.
Fetch the next digit (3) from the dividend, attach it to 565 and continue: 5653 / 645

Going ahead to step 5:
If we divide 5653 by 645, we get 8 and a remainder of 493.
The next digit of our result is 8. 
Result so far: 58.0
If we subtract 5160 from 5653, we get 493.
Take the next digit (8) from the dividend and append it to 493, then repeat: 4938 / 645

On to step 6:
4938 divided by 645 is 7 with a remainder of 423.
Put 7 as the next digit of the answer. 
Result so far: 587.0
If we take 4515 away from 4938, we end up with 423.
Append the next digit (3) from the dividend to 423 and continue with: 4233 / 645

Advancing to step 7:
When dividing 4233 by 645, we get 6 with a remainder of 363.
The number 6 becomes the next digit in our result. 
Result so far: 5876.0
Deduct 3870 from 4233 and we're left with 363.
Include the next digit (8) from the dividend after 363, then repeat: 3638 / 645

Moving on to step 8:
When dividing 3638 by 645, we get 5 with a remainder of 413.
Write down 5 as next digit of the result. 
Result so far: 58765.0
If we take 3225 away from 3638, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 9:
The number 645 fits into 4130 6 times, leaving a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 58765.6
The remainder is 260 after subtracting 3870 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
If we divide 2600 by 645, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 58765.64
If we subtract 2580 from 2600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 645, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 58765.64
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
645 can be fit into 2000 3 times, resulting in a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 58765.6403
Subtracting 1935 from 2000 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
645 can be fit into 650 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 58765.64031
If we take 645 away from 650, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
645 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 58765.64031
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
When dividing 500 by 645, we get 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 58765.64031
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 58765.64031 with a remaining 5e-06.
