37993654 ÷ 630 
We want to figure out the number of times 37993654 can be divided by 630.

Step 1:
If we divide 3 by 630, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 630

On to step 2:
630 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
Deduct 0 from 37 and we're left with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 630

Advancing to step 3:
If we divide 379 by 630, we get 0 and a remainder of 379.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 379 after subtracting 0 from 379.
Include the next digit (9) from the dividend after 379, then repeat: 3799 / 630

On to step 4:
630 can be fit into 3799 6 times, resulting in a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3780 from 3799, we get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 630

Advancing to step 5:
193 divided by 630 is 0 with a remainder of 193.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 193, we end up with 193.
Include the next digit (6) from the dividend after 193, then repeat: 1936 / 630

Let's proceed to step 6:
If we divide 1936 by 630, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
If we take 1890 away from 1936, we end up with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 630

On to step 7:
630 can be fit into 465 0 times, resulting in a remainder of 465.
The next digit of our result is 0. 
Result so far: 6030.0
Deduct 0 from 465 and we're left with 465.
Include the next digit (4) from the dividend after 465, then repeat: 4654 / 630

On to step 8:
630 can be fit into 4654 7 times, resulting in a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 60307.0
Subtracting 4410 from 4654 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
630 can be fit into 2440 3 times, resulting in a remainder of 550.
Use 3 as the next digit of our solution. 
Result so far: 60307.3
The remainder is 550 after subtracting 1890 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
5500 divided by 630 is 8 with a remainder of 460.
The number 8 becomes the next digit in our result. 
Result so far: 60307.38
If we take 5040 away from 5500, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
4600 divided by 630 is 7 with a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 60307.387
The remainder is 190 after subtracting 4410 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 12:
630 can be fit into 1900 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 60307.3873
Deduct 1890 from 1900 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 630, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 60307.3873
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
630 can be fit into 1000 1 times, resulting in a remainder of 370.
Record the quotient 1 as the next digit in the result. 
Result so far: 60307.387301
Subtracting 630 from 1000 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
630 can be fit into 3700 5 times, resulting in a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 60307.3873015
If we take 3150 away from 3700, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 16:
5500 divided by 630 is 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 60307.38730158
The remainder is 460 after subtracting 5040 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

After the division, we end up with 60307.38730158 and a remainder of 4.6e-07.
