We look at the division of 72121187 by 608 
We're looking to find how many times 608 goes into 72121187.

Going ahead to step 1:
When dividing 7 by 608, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 608

On to step 2:
When dividing 72 by 608, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 608

Step 3:
721 divided by 608 is 1 with a remainder of 113.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 608 from 721 to get 113.
Append the next digit (2) from the dividend to 113 and continue with: 1132 / 608

Let's proceed to step 4:
The number 608 fits into 1132 1 times, leaving a remainder of 524.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 608 from 1132 leaves us with 524.
Bring next digit (1) of the dividend behind the 524 and repeat the process: 5241 / 608

On to step 5:
5241 divided by 608 is 8 with a remainder of 377.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
The remainder is 377 after subtracting 4864 from 5241.
Take the next digit (1) from the dividend and append it to 377, then repeat: 3771 / 608

Step 6:
608 can be fit into 3771 6 times, resulting in a remainder of 123.
Use 6 as the next digit of our solution. 
Result so far: 1186.0
Subtracting 3648 from 3771 leaves us with 123.
Append the next digit (8) from the dividend to 123 and continue with: 1238 / 608

Advancing to step 7:
If we divide 1238 by 608, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 11862.0
If we subtract 1216 from 1238, we get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 608

Step 8:
If we divide 227 by 608, we get 0 and a remainder of 227.
Use 0 as the next digit of our solution. 
Result so far: 118620.0
If we subtract 0 from 227, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 9:
If we divide 2270 by 608, we get 3 and a remainder of 446.
Record the quotient 3 as the next digit in the result. 
Result so far: 118620.3
Subtracting 1824 from 2270 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 10:
4460 divided by 608 is 7 with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 118620.37
If we take 4256 away from 4460, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
608 can be fit into 2040 3 times, resulting in a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 118620.373
If we subtract 1824 from 2040, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 12:
The number 608 fits into 2160 3 times, leaving a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 118620.3733
Deduct 1824 from 2160 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 118620.3733 with a remainder of 0.00336.
