39415189 ÷ 254 
We want to figure out the number of times 39415189 can be divided by 254.

Going ahead to step 1:
3 divided by 254 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 254

On to step 2:
When dividing 39 by 254, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 254

On to step 3:
When dividing 394 by 254, we get 1 with a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 254 from 394, we get 140.
Append the next digit (1) from the dividend to 140 and continue with: 1401 / 254

Let's proceed to step 4:
254 goes into 1401 5 times with a remainder of 131.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 1270 from 1401 to get 131.
Fetch the next digit (5) from the dividend, attach it to 131 and continue: 1315 / 254

Let's proceed to step 5:
254 can be fit into 1315 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 155.0
Deduct 1270 from 1315 and we're left with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 254

Moving on to step 6:
451 divided by 254 is 1 with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 1551.0
Subtract 254 from 451 to get 197.
Include the next digit (8) from the dividend after 197, then repeat: 1978 / 254

Moving on to step 7:
The number 254 fits into 1978 7 times, leaving a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 15517.0
If we subtract 1778 from 1978, we get 200.
Take the next digit (9) from the dividend and append it to 200, then repeat: 2009 / 254

Let's proceed to step 8:
2009 divided by 254 is 7 with a remainder of 231.
Record the quotient 7 as the next digit in the result. 
Result so far: 155177.0
Deduct 1778 from 2009 and we're left 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.

Advancing to step 9:
254 goes into 2310 9 times with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 155177.9
If we subtract 2286 from 2310, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 254, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 155177.9
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
When dividing 2400 by 254, we get 9 with a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 155177.909
Subtracting 2286 from 2400 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 12:
254 can be fit into 1140 4 times, resulting in a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 155177.9094
Deduct 1016 from 1140 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 13:
When dividing 1240 by 254, we get 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 155177.90944
If we take 1016 away from 1240, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Our division results in 155177.90944 with a remaining 0.000224.
