We look at the division of 73961521 by 678 
We want to divide 73961521 by 678.

Moving on to step 1:
7 divided by 678 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 678

Advancing to step 2:
678 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 678

Going ahead to step 3:
When dividing 739 by 678, we get 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 678 from 739, we get 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 678

Step 4:
678 can be fit into 616 0 times, resulting in a remainder of 616.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 616, we get 616.
Take the next digit (1) from the dividend and append it to 616, then repeat: 6161 / 678

Step 5:
6161 divided by 678 is 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtract 6102 from 6161 to get 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 678

Let's proceed to step 6:
678 can be fit into 595 0 times, resulting in a remainder of 595.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
If we take 0 away from 595, we end up with 595.
Grab the next digit (2) from the dividend, add it to 595, then carry on: 5952 / 678

Advancing to step 7:
678 goes into 5952 8 times with a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 10908.0
If we take 5424 away from 5952, we end up with 528.
Fetch the next digit (1) from the dividend, attach it to 528 and continue: 5281 / 678

Step 8:
678 goes into 5281 7 times with a remainder of 535.
Record the quotient 7 as the next digit in the result. 
Result so far: 109087.0
Deduct 4746 from 5281 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 9:
678 can be fit into 5350 7 times, resulting in a remainder of 604.
The next digit of our result is 7. 
Result so far: 109087.7
The remainder is 604 after subtracting 4746 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 10:
If we divide 6040 by 678, we get 8 and a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 109087.78
Subtract 5424 from 6040 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 11:
678 goes into 6160 9 times with a remainder of 58.
Record the quotient 9 as the next digit in the result. 
Result so far: 109087.789
The remainder is 58 after subtracting 6102 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
678 can be fit into 580 0 times, resulting in a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 109087.789
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 13:
If we divide 5800 by 678, we get 8 and a remainder of 376.
The next digit of our result is 8. 
Result so far: 109087.78908
Deduct 5424 from 5800 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
3760 divided by 678 is 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 109087.789085
The remainder is 370 after subtracting 3390 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 15:
3700 divided by 678 is 5 with a remainder of 310.
The next digit of our result is 5. 
Result so far: 109087.7890855
Subtracting 3390 from 3700 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 109087.7890855, with a leftover of 3.1e-06.
