15629601 ÷ 672 
We're looking to find how many times 672 goes into 15629601.

On to step 1:
When dividing 1 by 672, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 672

Advancing to step 2:
The number 672 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 672

Going ahead to step 3:
If we divide 156 by 672, we get 0 and a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 156 and we're left with 156.
Take the next digit (2) from the dividend and append it to 156, then repeat: 1562 / 672

Let's proceed to step 4:
672 goes into 1562 2 times with a remainder of 218.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1344 from 1562 leaves us with 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 672

Let's proceed to step 5:
The number 672 fits into 2189 3 times, leaving a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 2016 away from 2189, we end up with 173.
Bring next digit (6) of the dividend behind the 173 and repeat the process: 1736 / 672

On to step 6:
672 can be fit into 1736 2 times, resulting in a remainder of 392.
Use 2 as the next digit of our solution. 
Result so far: 232.0
Subtract 1344 from 1736 to get 392.
Grab the next digit (0) from the dividend, add it to 392, then carry on: 3920 / 672

Advancing to step 7:
When dividing 3920 by 672, we get 5 with a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 2325.0
The remainder is 560 after subtracting 3360 from 3920.
Grab the next digit (1) from the dividend, add it to 560, then carry on: 5601 / 672

Let's proceed to step 8:
If we divide 5601 by 672, we get 8 and a remainder of 225.
The number 8 becomes the next digit in our result. 
Result so far: 23258.0
Subtract 5376 from 5601 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 9:
The number 672 fits into 2250 3 times, leaving a remainder of 234.
Put 3 as the next digit of the answer. 
Result so far: 23258.3
If we subtract 2016 from 2250, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 10:
When dividing 2340 by 672, we get 3 with a remainder of 324.
Put 3 as the next digit of the answer. 
Result so far: 23258.33
Subtracting 2016 from 2340 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 23258.33 with a remainder of 0.324.
