37038603 ÷ 668 
Let's see how many times 668 fits into 37038603.

Step 1:
If we divide 3 by 668, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 668

Step 2:
The number 668 fits into 37 0 times, leaving a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 668

Advancing to step 3:
370 divided by 668 is 0 with a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 370 and we're left with 370.
Fetch the next digit (3) from the dividend, attach it to 370 and continue: 3703 / 668

Moving on to step 4:
668 goes into 3703 5 times with a remainder of 363.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3340 from 3703, we get 363.
Bring next digit (8) of the dividend behind the 363 and repeat the process: 3638 / 668

Let's proceed to step 5:
When dividing 3638 by 668, we get 5 with a remainder of 298.
Use 5 as the next digit of our solution. 
Result so far: 55.0
The remainder is 298 after subtracting 3340 from 3638.
Append the next digit (6) from the dividend to 298 and continue with: 2986 / 668

On to step 6:
668 goes into 2986 4 times with a remainder of 314.
Write down 4 as next digit of the result. 
Result so far: 554.0
The remainder is 314 after subtracting 2672 from 2986.
Append the next digit (0) from the dividend to 314 and continue with: 3140 / 668

Advancing to step 7:
668 can be fit into 3140 4 times, resulting in a remainder of 468.
The number 4 becomes the next digit in our result. 
Result so far: 5544.0
If we subtract 2672 from 3140, we get 468.
Append the next digit (3) from the dividend to 468 and continue with: 4683 / 668

Advancing to step 8:
The number 668 fits into 4683 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 55447.0
Subtracting 4676 from 4683 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
When dividing 70 by 668, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 55447.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
700 divided by 668 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 55447.01
Subtracting 668 from 700 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 668, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 55447.01
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
If we divide 3200 by 668, we get 4 and a remainder of 528.
The number 4 becomes the next digit in our result. 
Result so far: 55447.0104
The remainder is 528 after subtracting 2672 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 13:
668 can be fit into 5280 7 times, resulting in a remainder of 604.
Record the quotient 7 as the next digit in the result. 
Result so far: 55447.01047
Subtract 4676 from 5280 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 14:
668 goes into 6040 9 times with a remainder of 28.
The next digit of our result is 9. 
Result so far: 55447.010479
The remainder is 28 after subtracting 6012 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
When dividing 280 by 668, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 55447.010479
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
2800 divided by 668 is 4 with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 55447.01047904
Subtracting 2672 from 2800 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 55447.01047904, with a leftover of 1.28e-07.
