We're dividing 978120 by 73 
We want to figure out the number of times 978120 can be divided by 73.

Advancing to step 1:
The number 73 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 73

Moving on to step 2:
73 can be fit into 97 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 73 from 97 to get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 73

Advancing to step 3:
If we divide 248 by 73, we get 3 and a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 219 away from 248, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 73

On to step 4:
If we divide 291 by 73, we get 3 and a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 219 away from 291, we end up with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 73

On to step 5:
If we divide 722 by 73, we get 9 and a remainder of 65.
The next digit of our result is 9. 
Result so far: 1339.0
Subtracting 657 from 722 leaves us with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 73

Moving on to step 6:
The number 73 fits into 650 8 times, leaving a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 13398.0
Subtracting 584 from 650 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
When dividing 660 by 73, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 13398.9
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
73 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 13398.9
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 73, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13398.904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 73, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 13398.9041
If we take 73 away from 80, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
73 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 13398.9041
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
73 goes into 700 9 times with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 13398.904109
Subtracting 657 from 700 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
The number 73 fits into 430 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 13398.9041095
Subtracting 365 from 430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
If we divide 650 by 73, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 13398.90410958
If we subtract 584 from 650, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 13398.90410958, with a leftover of 6.6e-08.
