We look at the division of 12957866 by 672 
We want to figure out the number of times 12957866 can be divided by 672.

Going ahead to step 1:
When dividing 1 by 672, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 672

Moving on to step 2:
672 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 672

Moving on to step 3:
The number 672 fits into 129 0 times, leaving a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Take the next digit (5) from the dividend and append it to 129, then repeat: 1295 / 672

Advancing to step 4:
If we divide 1295 by 672, we get 1 and a remainder of 623.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 672 from 1295 leaves us with 623.
Fetch the next digit (7) from the dividend, attach it to 623 and continue: 6237 / 672

Advancing to step 5:
If we divide 6237 by 672, we get 9 and a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 6048 from 6237 to get 189.
Take the next digit (8) from the dividend and append it to 189, then repeat: 1898 / 672

Step 6:
1898 divided by 672 is 2 with a remainder of 554.
The next digit of our result is 2. 
Result so far: 192.0
Deduct 1344 from 1898 and we're left with 554.
Grab the next digit (6) from the dividend, add it to 554, then carry on: 5546 / 672

On to step 7:
The number 672 fits into 5546 8 times, leaving a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 1928.0
If we take 5376 away from 5546, we end up with 170.
Grab the next digit (6) from the dividend, add it to 170, then carry on: 1706 / 672

Moving on to step 8:
When dividing 1706 by 672, we get 2 with a remainder of 362.
Write down 2 as next digit of the result. 
Result so far: 19282.0
The remainder is 362 after subtracting 1344 from 1706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
672 can be fit into 3620 5 times, resulting in a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 19282.5
The remainder is 260 after subtracting 3360 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
2600 divided by 672 is 3 with a remainder of 584.
The next digit of our result is 3. 
Result so far: 19282.53
Deduct 2016 from 2600 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 11:
When dividing 5840 by 672, we get 8 with a remainder of 464.
The next digit of our result is 8. 
Result so far: 19282.538
Deduct 5376 from 5840 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 12:
672 goes into 4640 6 times with a remainder of 608.
The next digit of our result is 6. 
Result so far: 19282.5386
Subtract 4032 from 4640 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
672 goes into 6080 9 times with a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 19282.53869
Subtracting 6048 from 6080 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
672 goes into 320 0 times with a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 19282.53869
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
If we divide 3200 by 672, we get 4 and a remainder of 512.
Use 4 as the next digit of our solution. 
Result so far: 19282.5386904
Deduct 2688 from 3200 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 16:
672 can be fit into 5120 7 times, resulting in a remainder of 416.
Record the quotient 7 as the next digit in the result. 
Result so far: 19282.53869047
Deduct 4704 from 5120 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The quotient of the division is 19282.53869047, and the remainder is 4.16e-07.
