We're dividing 73939906 by 78 
We're looking to find how many times 78 goes into 73939906.

Moving on to step 1:
7 divided by 78 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 78

Let's proceed to step 2:
If we divide 73 by 78, we get 0 and a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 78

Moving on to step 3:
When dividing 739 by 78, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 702 from 739, we get 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 78

Advancing to step 4:
When dividing 373 by 78, we get 4 with a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 312 from 373 and we're left with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 78

Step 5:
The number 78 fits into 619 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 947.0
Subtracting 546 from 619 leaves us with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 78

Step 6:
When dividing 739 by 78, we get 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9479.0
If we take 702 away from 739, we end up with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 78

Advancing to step 7:
370 divided by 78 is 4 with a remainder of 58.
The next digit of our result is 4. 
Result so far: 94794.0
Deduct 312 from 370 and we're left with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 78

Going ahead to step 8:
The number 78 fits into 586 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 947947.0
Subtract 546 from 586 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
400 divided by 78 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 947947.5
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 947947.51
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 947947.512
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 947947.5128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 78 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 947947.51282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 78, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 947947.51282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
400 divided by 78 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 947947.5128205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 78, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 947947.51282051
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 947947.51282051 with a remaining 2.2e-08.
