When dividing 5 by 1, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Let's proceed to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 3 from 3, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Step 3:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 534.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Result so far: 5344.0
Subtract 4 from 4 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 5:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 53443.0
If we take 3 away from 3, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 6:
1 goes into 8 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 534438.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Going ahead to step 7:
When dividing 7 by 1, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 5344387.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 8:
When dividing 6 by 1, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 53443876.0
If we subtract 6 from 6, 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.

On to step 9:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53443876.0
Subtract 0 from 0 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 10:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53443876.0
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.
