We look at the division of 39919768 by 154 
We're looking to find how many times 154 goes into 39919768.

Step 1:
154 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 154

Advancing to step 2:
154 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 154

Moving on to step 3:
If we divide 399 by 154, we get 2 and a remainder of 91.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 308 from 399 and we're left with 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 154

Step 4:
If we divide 911 by 154, we get 5 and a remainder of 141.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 770 away from 911, we end up with 141.
Bring next digit (9) of the dividend behind the 141 and repeat the process: 1419 / 154

Step 5:
When dividing 1419 by 154, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 259.0
If we subtract 1386 from 1419, we get 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 154

Moving on to step 6:
The number 154 fits into 337 2 times, leaving a remainder of 29.
The next digit of our result is 2. 
Result so far: 2592.0
The remainder is 29 after subtracting 308 from 337.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 154

On to step 7:
The number 154 fits into 296 1 times, leaving a remainder of 142.
Use 1 as the next digit of our solution. 
Result so far: 25921.0
Subtracting 154 from 296 leaves us with 142.
Fetch the next digit (8) from the dividend, attach it to 142 and continue: 1428 / 154

Advancing to step 8:
154 can be fit into 1428 9 times, resulting in a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 259219.0
If we subtract 1386 from 1428, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
154 can be fit into 420 2 times, resulting in a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 259219.2
Deduct 308 from 420 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
154 can be fit into 1120 7 times, resulting in a remainder of 42.
The next digit of our result is 7. 
Result so far: 259219.27
If we subtract 1078 from 1120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
154 goes into 420 2 times with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 259219.272
Subtracting 308 from 420 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 12:
When dividing 1120 by 154, we get 7 with a remainder of 42.
The next digit of our result is 7. 
Result so far: 259219.2727
Deduct 1078 from 1120 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
420 divided by 154 is 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 259219.27272
If we subtract 308 from 420, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 14:
1120 divided by 154 is 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 259219.272727
If we subtract 1078 from 1120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 15:
154 goes into 420 2 times with a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 259219.2727272
If we take 308 away from 420, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 16:
The number 154 fits into 1120 7 times, leaving a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 259219.27272727
The remainder is 42 after subtracting 1078 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 259219.27272727, with a leftover of 4.2e-08.
