We divide 851321 by 78
We want to figure out the number of times 851321 can be divided by 78.

Advancing to step 1:
8 divided by 78 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 78

On to step 2:
78 goes into 85 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 78 from 85 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 78

Moving on to step 3:
If we divide 71 by 78, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 71 to get 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 78

Moving on to step 4:
78 goes into 713 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
If we subtract 702 from 713, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 78

Advancing to step 5:
When dividing 112 by 78, we get 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1091.0
Subtracting 78 from 112 leaves us with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 78

On to step 6:
If we divide 341 by 78, we get 4 and a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 10914.0
If we subtract 312 from 341, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
78 can be fit into 290 3 times, resulting in a remainder of 56.
The next digit of our result is 3. 
Result so far: 10914.3
If we take 234 away from 290, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 78 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 10914.37
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 78 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 10914.371
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 10914.3717
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
When dividing 740 by 78, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 10914.37179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
If we divide 380 by 78, we get 4 and a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 10914.371794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
78 goes into 680 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 10914.3717948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
If we divide 560 by 78, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 10914.37179487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 10914.37179487, and the remainder is 1.4e-08.
