We look at the division of 78697053 by 154 
Let's see how many times 154 fits into 78697053.

Going ahead to step 1:
7 divided by 154 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 154

Going ahead to step 2:
154 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 154

Advancing to step 3:
The number 154 fits into 786 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 770 from 786 leaves us with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 154

Going ahead to step 4:
When dividing 169 by 154, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 154 from 169, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 154

Moving on to step 5:
When dividing 157 by 154, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 511.0
If we subtract 154 from 157, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 154

Going ahead to step 6:
When dividing 30 by 154, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5110.0
Subtract 0 from 30 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 154

On to step 7:
When dividing 305 by 154, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 51101.0
The remainder is 151 after subtracting 154 from 305.
Grab the next digit (3) from the dividend, add it to 151, then carry on: 1513 / 154

Moving on to step 8:
When dividing 1513 by 154, we get 9 with a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 511019.0
If we subtract 1386 from 1513, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
1270 divided by 154 is 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 511019.8
If we take 1232 away from 1270, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
154 goes into 380 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 511019.82
Deduct 308 from 380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
154 can be fit into 720 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 511019.824
Subtracting 616 from 720 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
154 can be fit into 1040 6 times, resulting in a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 511019.8246
If we take 924 away from 1040, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 13:
1160 divided by 154 is 7 with a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 511019.82467
Subtracting 1078 from 1160 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 14:
The number 154 fits into 820 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 511019.824675
If we take 770 away from 820, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
If we divide 500 by 154, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 511019.8246753
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 16:
154 can be fit into 380 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 511019.82467532
Deduct 308 from 380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 511019.82467532 and a remainder of 7.2e-08.
