We're dividing 39949381 by 600 
We want to figure out the number of times 39949381 can be divided by 600.

Advancing to step 1:
The number 600 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 600

Moving on to step 2:
If we divide 39 by 600, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 600

Advancing to step 3:
600 can be fit into 399 0 times, resulting in a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 399, we end up with 399.
Include the next digit (4) from the dividend after 399, then repeat: 3994 / 600

Going ahead to step 4:
3994 divided by 600 is 6 with a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 3600 from 3994 and we're left with 394.
Grab the next digit (9) from the dividend, add it to 394, then carry on: 3949 / 600

Advancing to step 5:
If we divide 3949 by 600, we get 6 and a remainder of 349.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 349 after subtracting 3600 from 3949.
Include the next digit (3) from the dividend after 349, then repeat: 3493 / 600

Going ahead to step 6:
600 goes into 3493 5 times with a remainder of 493.
The number 5 becomes the next digit in our result. 
Result so far: 665.0
Subtract 3000 from 3493 to get 493.
Bring next digit (8) of the dividend behind the 493 and repeat the process: 4938 / 600

Going ahead to step 7:
If we divide 4938 by 600, we get 8 and a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 6658.0
Subtract 4800 from 4938 to get 138.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 600

Moving on to step 8:
600 can be fit into 1381 2 times, resulting in a remainder of 181.
Write down 2 as next digit of the result. 
Result so far: 66582.0
Subtract 1200 from 1381 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 9:
1810 divided by 600 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 66582.3
The remainder is 10 after subtracting 1800 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
600 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 66582.3
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
If we divide 1000 by 600, we get 1 and a remainder of 400.
The next digit of our result is 1. 
Result so far: 66582.301
If we take 600 away from 1000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
If we divide 4000 by 600, we get 6 and a remainder of 400.
Record the quotient 6 as the next digit in the result. 
Result so far: 66582.3016
If we take 3600 away from 4000, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
600 can be fit into 4000 6 times, resulting in a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 66582.30166
The remainder is 400 after subtracting 3600 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 66582.30166, with a leftover of 0.0004.
