53158816 ÷ 629 
We want to divide 53158816 by 629.

On to step 1:
If we divide 5 by 629, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 629

Moving on to step 2:
When dividing 53 by 629, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 629

Advancing to step 3:
629 can be fit into 531 0 times, resulting in a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 531 to get 531.
Bring next digit (5) of the dividend behind the 531 and repeat the process: 5315 / 629

Step 4:
If we divide 5315 by 629, we get 8 and a remainder of 283.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5032 from 5315 leaves us with 283.
Append the next digit (8) from the dividend to 283 and continue with: 2838 / 629

On to step 5:
If we divide 2838 by 629, we get 4 and a remainder of 322.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 2516 away from 2838, we end up with 322.
Grab the next digit (8) from the dividend, add it to 322, then carry on: 3228 / 629

Let's proceed to step 6:
3228 divided by 629 is 5 with a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 845.0
Subtracting 3145 from 3228 leaves us with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 629

Let's proceed to step 7:
831 divided by 629 is 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 8451.0
Deduct 629 from 831 and we're left with 202.
Grab the next digit (6) from the dividend, add it to 202, then carry on: 2026 / 629

Advancing to step 8:
629 can be fit into 2026 3 times, resulting in a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 84513.0
The remainder is 139 after subtracting 1887 from 2026.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
The number 629 fits into 1390 2 times, leaving a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 84513.2
If we take 1258 away from 1390, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
629 goes into 1320 2 times with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 84513.22
Deduct 1258 from 1320 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 84513.22 and a remainder of 0.062.
