We look at the division of 77958511 by 154 
Our goal is to divide 77958511 by 154.

Advancing to step 1:
154 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 154

Advancing to step 2:
154 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 154

Going ahead to step 3:
When dividing 779 by 154, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 770 from 779 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 154

Let's proceed to step 4:
95 divided by 154 is 0 with a remainder of 95.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 95, we get 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 154

Moving on to step 5:
When dividing 958 by 154, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 506.0
Deduct 924 from 958 and we're left with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 154

On to step 6:
154 can be fit into 345 2 times, resulting in a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 5062.0
Subtract 308 from 345 to get 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 154

On to step 7:
If we divide 371 by 154, we get 2 and a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 50622.0
If we subtract 308 from 371, we get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 154

Advancing to step 8:
The number 154 fits into 631 4 times, leaving a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 506224.0
Subtracting 616 from 631 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
If we divide 150 by 154, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 506224.0
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
When dividing 1500 by 154, we get 9 with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 506224.09
Subtracting 1386 from 1500 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.

On to step 11:
If we divide 1140 by 154, we get 7 and a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 506224.097
The remainder is 62 after subtracting 1078 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
If we divide 620 by 154, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 506224.0974
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 154, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 506224.0974
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
When dividing 400 by 154, we get 2 with a remainder of 92.
Write down 2 as next digit of the result. 
Result so far: 506224.097402
Deduct 308 from 400 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 15:
154 can be fit into 920 5 times, resulting in a remainder of 150.
The next digit of our result is 5. 
Result so far: 506224.0974025
Subtracting 770 from 920 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 16:
154 goes into 1500 9 times with a remainder of 114.
Use 9 as the next digit of our solution. 
Result so far: 506224.09740259
If we take 1386 away from 1500, we end up 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.

Our division results in 506224.09740259 with a remaining 1.14e-07.
