Let's divide 12970388 by 667
We want to divide 12970388 by 667.

Going ahead to step 1:
When dividing 1 by 667, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 667

Advancing to step 2:
If we divide 12 by 667, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 667

Step 3:
When dividing 129 by 667, we get 0 with a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Grab the next digit (7) from the dividend, add it to 129, then carry on: 1297 / 667

Let's proceed to step 4:
667 can be fit into 1297 1 times, resulting in a remainder of 630.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 667 from 1297, we get 630.
Grab the next digit (0) from the dividend, add it to 630, then carry on: 6300 / 667

Moving on to step 5:
667 can be fit into 6300 9 times, resulting in a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 297 after subtracting 6003 from 6300.
Grab the next digit (3) from the dividend, add it to 297, then carry on: 2973 / 667

Advancing to step 6:
The number 667 fits into 2973 4 times, leaving a remainder of 305.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Subtracting 2668 from 2973 leaves us with 305.
Append the next digit (8) from the dividend to 305 and continue with: 3058 / 667

Let's proceed to step 7:
If we divide 3058 by 667, we get 4 and a remainder of 390.
Record the quotient 4 as the next digit in the result. 
Result so far: 1944.0
Subtract 2668 from 3058 to get 390.
Include the next digit (8) from the dividend after 390, then repeat: 3908 / 667

Advancing to step 8:
The number 667 fits into 3908 5 times, leaving a remainder of 573.
Write down 5 as next digit of the result. 
Result so far: 19445.0
Deduct 3335 from 3908 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

On to step 9:
The number 667 fits into 5730 8 times, leaving a remainder of 394.
Write down 8 as next digit of the result. 
Result so far: 19445.8
The remainder is 394 after subtracting 5336 from 5730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
3940 divided by 667 is 5 with a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 19445.85
If we subtract 3335 from 3940, we get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Step 11:
667 can be fit into 6050 9 times, resulting in a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 19445.859
Subtracting 6003 from 6050 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 12:
If we divide 470 by 667, we get 0 and a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 19445.859
If we take 0 away from 470, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 13:
4700 divided by 667 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 19445.85907
If we take 4669 away from 4700, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
The number 667 fits into 310 0 times, leaving a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 19445.85907
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 15:
If we divide 3100 by 667, we get 4 and a remainder of 432.
Put 4 as the next digit of the answer. 
Result so far: 19445.8590704
If we take 2668 away from 3100, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 16:
The number 667 fits into 4320 6 times, leaving a remainder of 318.
Use 6 as the next digit of our solution. 
Result so far: 19445.85907046
If we subtract 4002 from 4320, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

In conclusion, the division gives 19445.85907046 with a balance of 3.18e-07.
