51381481 ÷ 125 
We want to divide 51381481 by 125.

Moving on to step 1:
If we divide 5 by 125, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 125

Let's proceed to step 2:
When dividing 51 by 125, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 125

Going ahead to step 3:
If we divide 513 by 125, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 500 from 513, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 125

Going ahead to step 4:
When dividing 138 by 125, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 125 from 138 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 125

On to step 5:
When dividing 131 by 125, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 411.0
The remainder is 6 after subtracting 125 from 131.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 125

Step 6:
When dividing 64 by 125, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 4110.0
If we subtract 0 from 64, we get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 125

Going ahead to step 7:
648 divided by 125 is 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 41105.0
Deduct 625 from 648 and we're left with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 125

Step 8:
125 goes into 231 1 times with a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 411051.0
Deduct 125 from 231 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
The number 125 fits into 1060 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 411051.8
If we subtract 1000 from 1060, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
125 can be fit into 600 4 times, resulting in a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 411051.84
The remainder is 100 after subtracting 500 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
If we divide 1000 by 125, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 411051.848
If we take 1000 away from 1000, 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.

On to step 12:
The number 125 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 411051.848
Deduct 0 from 0 and we're left 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 13:
0 divided by 125 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 411051.848
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.

In conclusion, the division gives 411051.848 with a balance of 0.0.
