38606421 ÷ 637 
We want to figure out the number of times 38606421 can be divided by 637.

Advancing to step 1:
637 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 637

Going ahead to step 2:
637 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 637

On to step 3:
When dividing 386 by 637, we get 0 with a remainder of 386.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 386, we end up with 386.
Include the next digit (0) from the dividend after 386, then repeat: 3860 / 637

Advancing to step 4:
637 goes into 3860 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3822 from 3860 and we're left with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 637

Advancing to step 5:
386 divided by 637 is 0 with a remainder of 386.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
The remainder is 386 after subtracting 0 from 386.
Append the next digit (4) from the dividend to 386 and continue with: 3864 / 637

On to step 6:
If we divide 3864 by 637, we get 6 and a remainder of 42.
The next digit of our result is 6. 
Result so far: 606.0
Subtract 3822 from 3864 to get 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 637

On to step 7:
637 can be fit into 422 0 times, resulting in a remainder of 422.
Record the quotient 0 as the next digit in the result. 
Result so far: 6060.0
Subtract 0 from 422 to get 422.
Fetch the next digit (1) from the dividend, attach it to 422 and continue: 4221 / 637

Moving on to step 8:
637 goes into 4221 6 times with a remainder of 399.
Record the quotient 6 as the next digit in the result. 
Result so far: 60606.0
The remainder is 399 after subtracting 3822 from 4221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 9:
637 can be fit into 3990 6 times, resulting in a remainder of 168.
The next digit of our result is 6. 
Result so far: 60606.6
Subtracting 3822 from 3990 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 10:
When dividing 1680 by 637, we get 2 with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 60606.62
If we subtract 1274 from 1680, we get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 11:
When dividing 4060 by 637, we get 6 with a remainder of 238.
Use 6 as the next digit of our solution. 
Result so far: 60606.626
If we take 3822 away from 4060, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 12:
637 can be fit into 2380 3 times, resulting in a remainder of 469.
The next digit of our result is 3. 
Result so far: 60606.6263
The remainder is 469 after subtracting 1911 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 13:
The number 637 fits into 4690 7 times, leaving a remainder of 231.
Use 7 as the next digit of our solution. 
Result so far: 60606.62637
Subtracting 4459 from 4690 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 14:
When dividing 2310 by 637, we get 3 with a remainder of 399.
Record the quotient 3 as the next digit in the result. 
Result so far: 60606.626373
Deduct 1911 from 2310 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

On to step 15:
When dividing 3990 by 637, we get 6 with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 60606.6263736
The remainder is 168 after subtracting 3822 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 16:
The number 637 fits into 1680 2 times, leaving a remainder of 406.
The number 2 becomes the next digit in our result. 
Result so far: 60606.62637362
If we take 1274 away from 1680, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The quotient of the division is 60606.62637362, and the remainder is 4.06e-07.
