42551962 ÷ 8 
We're looking to find how many times 8 goes into 42551962.

Advancing to step 1:
8 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 8

Let's proceed to step 2:
42 divided by 8 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 40 from 42 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 8

Moving on to step 3:
When dividing 25 by 8, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 24 from 25 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 8

Going ahead to step 4:
8 can be fit into 15 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 531.0
Subtract 8 from 15 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 8

Moving on to step 5:
When dividing 71 by 8, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 5318.0
If we subtract 64 from 71, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 8

On to step 6:
8 goes into 79 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 53189.0
If we take 72 away from 79, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 8

On to step 7:
When dividing 76 by 8, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 531899.0
Deduct 72 from 76 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 8

Going ahead to step 8:
42 divided by 8 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5318995.0
The remainder is 2 after subtracting 40 from 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 8, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 5318995.2
Subtracting 16 from 20 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5318995.25
Subtract 40 from 40 to 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.

Moving on to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5318995.25
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 12:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5318995.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5318995.25, with a leftover of 0.0.
