851937 ÷ 78 
Let's see how many times 78 fits into 851937.

Going ahead to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 78

Step 2:
If we divide 85 by 78, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 78 from 85, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 78

Going ahead to step 3:
When dividing 71 by 78, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 71, we get 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 78

On to step 4:
78 goes into 719 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we subtract 702 from 719, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 78

Moving on to step 5:
173 divided by 78 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 1092.0
The remainder is 17 after subtracting 156 from 173.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 78

Step 6:
78 goes into 177 2 times with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 10922.0
If we subtract 156 from 177, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 78 fits into 210 2 times, leaving a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 10922.2
If we take 156 away from 210, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
540 divided by 78 is 6 with a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 10922.26
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
78 goes into 720 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 10922.269
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 10922.2692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 10922.26923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
If we divide 60 by 78, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10922.26923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
If we divide 600 by 78, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 10922.2692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 10922.26923076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 10922.26923076 with a balance of 7.2e-08.
