Let's divide 51400872 by 125
We want to divide 51400872 by 125.

Moving on to step 1:
5 divided by 125 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 125

Let's proceed to step 2:
51 divided by 125 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 125

On to step 3:
If we divide 514 by 125, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 500 from 514 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 125

Moving on to step 4:
140 divided by 125 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtracting 125 from 140 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 125

Advancing to step 5:
125 can be fit into 150 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
If we subtract 125 from 150, we get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 125

Advancing to step 6:
125 can be fit into 258 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4112.0
If we subtract 250 from 258, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 125

Advancing to step 7:
When dividing 87 by 125, we get 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 41120.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 125

Moving on to step 8:
125 can be fit into 872 6 times, resulting in a remainder of 122.
The next digit of our result is 6. 
Result so far: 411206.0
Deduct 750 from 872 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
125 can be fit into 1220 9 times, resulting in a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 411206.9
If we subtract 1125 from 1220, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
The number 125 fits into 950 7 times, leaving a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 411206.97
If we take 875 away from 950, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
750 divided by 125 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 411206.976
If we take 750 away from 750, 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.

Step 12:
If we divide 0 by 125, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 411206.976
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.

On to step 13:
When dividing 0 by 125, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 411206.976
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.

The quotient of the division is 411206.976, and the remainder is 0.0.
