Let's divide 81993724 by 672
We're looking to find how many times 672 goes into 81993724.

Advancing to step 1:
672 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 672

Let's proceed to step 2:
81 divided by 672 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 672

Moving on to step 3:
When dividing 819 by 672, we get 1 with a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 672 from 819 leaves us with 147.
Take the next digit (9) from the dividend and append it to 147, then repeat: 1479 / 672

Step 4:
When dividing 1479 by 672, we get 2 with a remainder of 135.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 135 after subtracting 1344 from 1479.
Bring next digit (3) of the dividend behind the 135 and repeat the process: 1353 / 672

Let's proceed to step 5:
The number 672 fits into 1353 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 122.0
The remainder is 9 after subtracting 1344 from 1353.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 672

On to step 6:
When dividing 97 by 672, we get 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 1220.0
If we take 0 away from 97, we end up with 97.
Take the next digit (2) from the dividend and append it to 97, then repeat: 972 / 672

Advancing to step 7:
672 can be fit into 972 1 times, resulting in a remainder of 300.
The number 1 becomes the next digit in our result. 
Result so far: 12201.0
Deduct 672 from 972 and we're left with 300.
Append the next digit (4) from the dividend to 300 and continue with: 3004 / 672

Let's proceed to step 8:
The number 672 fits into 3004 4 times, leaving a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 122014.0
The remainder is 316 after subtracting 2688 from 3004.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 9:
3160 divided by 672 is 4 with a remainder of 472.
Write down 4 as next digit of the result. 
Result so far: 122014.4
Subtract 2688 from 3160 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 10:
672 goes into 4720 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 122014.47
The remainder is 16 after subtracting 4704 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
672 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 122014.47
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
The number 672 fits into 1600 2 times, leaving a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 122014.4702
Deduct 1344 from 1600 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
2560 divided by 672 is 3 with a remainder of 544.
The number 3 becomes the next digit in our result. 
Result so far: 122014.47023
The remainder is 544 after subtracting 2016 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 14:
If we divide 5440 by 672, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 122014.470238
Subtracting 5376 from 5440 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
640 divided by 672 is 0 with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 122014.470238
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
If we divide 6400 by 672, we get 9 and a remainder of 352.
Record the quotient 9 as the next digit in the result. 
Result so far: 122014.47023809
If we subtract 6048 from 6400, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final outcome is 122014.47023809, with a leftover of 3.52e-07.
