151620 ÷ 6 
We want to figure out the number of times 151620 can be divided by 6.

On to step 1:
1 divided by 6 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 6

Advancing to step 2:
15 divided by 6 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 3 after subtracting 12 from 15.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 6

Step 3:
When dividing 31 by 6, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 30 from 31 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 6

Advancing to step 4:
When dividing 16 by 6, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
If we subtract 12 from 16, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 6

Moving on to step 5:
The number 6 fits into 42 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 2527.0
Deduct 42 from 42 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 6

On to step 6:
0 divided by 6 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25270.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 6 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25270.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
6 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25270.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 25270.0 and a remainder of 0.0.
