We look at the division of 30691255 by 658 
Let's see how many times 658 fits into 30691255.

Advancing to step 1:
If we divide 3 by 658, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 658

On to step 2:
If we divide 30 by 658, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 658

Moving on to step 3:
658 goes into 306 0 times with a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Take the next digit (9) from the dividend and append it to 306, then repeat: 3069 / 658

Step 4:
658 goes into 3069 4 times with a remainder of 437.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2632 away from 3069, we end up with 437.
Include the next digit (1) from the dividend after 437, then repeat: 4371 / 658

Let's proceed to step 5:
When dividing 4371 by 658, we get 6 with a remainder of 423.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 3948 from 4371 and we're left with 423.
Grab the next digit (2) from the dividend, add it to 423, then carry on: 4232 / 658

On to step 6:
The number 658 fits into 4232 6 times, leaving a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
The remainder is 284 after subtracting 3948 from 4232.
Grab the next digit (5) from the dividend, add it to 284, then carry on: 2845 / 658

Advancing to step 7:
The number 658 fits into 2845 4 times, leaving a remainder of 213.
Use 4 as the next digit of our solution. 
Result so far: 4664.0
Deduct 2632 from 2845 and we're left with 213.
Take the next digit (5) from the dividend and append it to 213, then repeat: 2135 / 658

Step 8:
2135 divided by 658 is 3 with a remainder of 161.
The next digit of our result is 3. 
Result so far: 46643.0
If we subtract 1974 from 2135, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 9:
1610 divided by 658 is 2 with a remainder of 294.
Put 2 as the next digit of the answer. 
Result so far: 46643.2
Subtracting 1316 from 1610 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 10:
2940 divided by 658 is 4 with a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 46643.24
If we subtract 2632 from 2940, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
If we divide 3080 by 658, we get 4 and a remainder of 448.
The next digit of our result is 4. 
Result so far: 46643.244
If we subtract 2632 from 3080, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 46643.244, with a leftover of 0.0448.
