Let's divide 943855 by 78
We want to figure out the number of times 943855 can be divided by 78.

Step 1:
78 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 78

Advancing to step 2:
The number 78 fits into 94 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 78 from 94 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 78

On to step 3:
78 can be fit into 163 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 156 from 163 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 78

Step 4:
78 divided by 78 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
Subtract 78 from 78 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 78

Moving on to step 5:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 1210.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 78

Let's proceed to step 6:
The number 78 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 12100.0
Subtract 0 from 55 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
If we divide 550 by 78, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 12100.7
Deduct 546 from 550 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 78 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12100.7
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 78, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 12100.705
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 78 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 12100.7051
If we subtract 78 from 100, we 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.

Advancing to step 11:
When dividing 220 by 78, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 12100.70512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
78 goes into 640 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 12100.705128
Subtracting 624 from 640 leaves us 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.

On to step 13:
If we divide 160 by 78, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12100.7051282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
When dividing 40 by 78, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12100.7051282
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.

The quotient of the division is 12100.7051282, and the remainder is 4e-08.
