We look at the division of 81949512 by 672 
Let's see how many times 672 fits into 81949512.

On to step 1:
If we divide 8 by 672, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 672

Advancing to step 2:
81 divided by 672 is 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 672

Advancing to step 3:
The number 672 fits into 819 1 times, leaving a remainder of 147.
The next digit of our result is 1. 
Result so far: 1.0
If we take 672 away from 819, we end up with 147.
Include the next digit (4) from the dividend after 147, then repeat: 1474 / 672

Let's proceed to step 4:
672 can be fit into 1474 2 times, resulting in a remainder of 130.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1344 from 1474 to get 130.
Append the next digit (9) from the dividend to 130 and continue with: 1309 / 672

Step 5:
1309 divided by 672 is 1 with a remainder of 637.
Put 1 as the next digit of the answer. 
Result so far: 121.0
If we subtract 672 from 1309, we get 637.
Append the next digit (5) from the dividend to 637 and continue with: 6375 / 672

Let's proceed to step 6:
672 can be fit into 6375 9 times, resulting in a remainder of 327.
Put 9 as the next digit of the answer. 
Result so far: 1219.0
Deduct 6048 from 6375 and we're left with 327.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 672

On to step 7:
672 goes into 3271 4 times with a remainder of 583.
Put 4 as the next digit of the answer. 
Result so far: 12194.0
If we subtract 2688 from 3271, we get 583.
Take the next digit (2) from the dividend and append it to 583, then repeat: 5832 / 672

Let's proceed to step 8:
5832 divided by 672 is 8 with a remainder of 456.
Write down 8 as next digit of the result. 
Result so far: 121948.0
If we take 5376 away from 5832, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 9:
672 goes into 4560 6 times with a remainder of 528.
Use 6 as the next digit of our solution. 
Result so far: 121948.6
Deduct 4032 from 4560 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 10:
When dividing 5280 by 672, we get 7 with a remainder of 576.
The number 7 becomes the next digit in our result. 
Result so far: 121948.67
Subtracting 4704 from 5280 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 11:
672 goes into 5760 8 times with a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 121948.678
The remainder is 384 after subtracting 5376 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
When dividing 3840 by 672, we get 5 with a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 121948.6785
The remainder is 480 after subtracting 3360 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
When dividing 4800 by 672, we get 7 with a remainder of 96.
Write down 7 as next digit of the result. 
Result so far: 121948.67857
Subtracting 4704 from 4800 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
If we divide 960 by 672, we get 1 and a remainder of 288.
Record the quotient 1 as the next digit in the result. 
Result so far: 121948.678571
The remainder is 288 after subtracting 672 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
The number 672 fits into 2880 4 times, leaving a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 121948.6785714
Subtract 2688 from 2880 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 16:
If we divide 1920 by 672, we get 2 and a remainder of 576.
Use 2 as the next digit of our solution. 
Result so far: 121948.67857142
The remainder is 576 after subtracting 1344 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

After the division, we end up with 121948.67857142 and a remainder of 5.76e-07.
