78240546 ÷ 169 
Our goal is to divide 78240546 by 169.

On to step 1:
When dividing 7 by 169, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 169

Step 2:
If we divide 78 by 169, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 169

Moving on to step 3:
169 goes into 782 4 times with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 676 from 782, we get 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 169

On to step 4:
169 goes into 1064 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 1014 from 1064 leaves us with 50.
Take the next digit (0) from the dividend and append it to 50, then repeat: 500 / 169

Going ahead to step 5:
169 goes into 500 2 times with a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 462.0
Subtracting 338 from 500 leaves us with 162.
Append the next digit (5) from the dividend to 162 and continue with: 1625 / 169

Going ahead to step 6:
The number 169 fits into 1625 9 times, leaving a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 4629.0
Subtracting 1521 from 1625 leaves us with 104.
Grab the next digit (4) from the dividend, add it to 104, then carry on: 1044 / 169

Moving on to step 7:
169 can be fit into 1044 6 times, resulting in a remainder of 30.
The next digit of our result is 6. 
Result so far: 46296.0
Subtract 1014 from 1044 to get 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 169

On to step 8:
When dividing 306 by 169, we get 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 462961.0
Deduct 169 from 306 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
When dividing 1370 by 169, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 462961.8
The remainder is 18 after subtracting 1352 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 169 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 462961.81
Deduct 169 from 180 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 169, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 462961.81
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 12:
1100 divided by 169 is 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 462961.8106
If we take 1014 away from 1100, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 13:
860 divided by 169 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 462961.81065
Subtracting 845 from 860 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.

Step 14:
169 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 462961.81065
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
1500 divided by 169 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 462961.8106508
Subtracting 1352 from 1500 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 16:
1480 divided by 169 is 8 with a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 462961.81065088
If we subtract 1352 from 1480, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 462961.81065088, with a leftover of 1.28e-07.
