78122387 divided by 670 
Our goal is to divide 78122387 by 670.

Advancing to step 1:
If we divide 7 by 670, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 670

Advancing to step 2:
670 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 670

Let's proceed to step 3:
670 can be fit into 781 1 times, resulting in a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 670 from 781, we get 111.
Take the next digit (2) from the dividend and append it to 111, then repeat: 1112 / 670

Going ahead to step 4:
670 goes into 1112 1 times with a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 442 after subtracting 670 from 1112.
Bring next digit (2) of the dividend behind the 442 and repeat the process: 4422 / 670

Step 5:
4422 divided by 670 is 6 with a remainder of 402.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 4020 from 4422 and we're left with 402.
Take the next digit (3) from the dividend and append it to 402, then repeat: 4023 / 670

Advancing to step 6:
When dividing 4023 by 670, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1166.0
Subtracting 4020 from 4023 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 670

Moving on to step 7:
670 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 11660.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 670

Let's proceed to step 8:
When dividing 387 by 670, we get 0 with a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 116600.0
The remainder is 387 after subtracting 0 from 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
670 can be fit into 3870 5 times, resulting in a remainder of 520.
Use 5 as the next digit of our solution. 
Result so far: 116600.5
Deduct 3350 from 3870 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
670 can be fit into 5200 7 times, resulting in a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 116600.57
Deduct 4690 from 5200 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 11:
The number 670 fits into 5100 7 times, leaving a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 116600.577
Deduct 4690 from 5100 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

In conclusion, the division gives 116600.577 with a balance of 0.041.
