78663931 ÷ 169 
Our goal is to divide 78663931 by 169.

On to step 1:
169 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
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 / 169

Step 2:
78 divided by 169 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 169

Let's proceed to step 3:
If we divide 786 by 169, we get 4 and a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 676 from 786 and we're left with 110.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 169

Moving on to step 4:
1106 divided by 169 is 6 with a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 92 after subtracting 1014 from 1106.
Append the next digit (3) from the dividend to 92 and continue with: 923 / 169

Going ahead to step 5:
169 goes into 923 5 times with a remainder of 78.
The next digit of our result is 5. 
Result so far: 465.0
Subtract 845 from 923 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 169

Let's proceed to step 6:
169 goes into 789 4 times with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 4654.0
If we subtract 676 from 789, we get 113.
Fetch the next digit (3) from the dividend, attach it to 113 and continue: 1133 / 169

On to step 7:
If we divide 1133 by 169, we get 6 and a remainder of 119.
Use 6 as the next digit of our solution. 
Result so far: 46546.0
Subtracting 1014 from 1133 leaves us with 119.
Grab the next digit (1) from the dividend, add it to 119, then carry on: 1191 / 169

Let's proceed to step 8:
If we divide 1191 by 169, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 465467.0
Deduct 1183 from 1191 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
169 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 465467.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
When dividing 800 by 169, we get 4 with a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 465467.04
The remainder is 124 after subtracting 676 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 11:
If we divide 1240 by 169, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 465467.047
If we take 1183 away from 1240, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
When dividing 570 by 169, we get 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 465467.0473
Subtracting 507 from 570 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 13:
If we divide 630 by 169, we get 3 and a remainder of 123.
Use 3 as the next digit of our solution. 
Result so far: 465467.04733
Subtracting 507 from 630 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

In conclusion, the division gives 465467.04733 with a balance of 0.000123.
