We look at the division of 151457 by 51 
We want to figure out the number of times 151457 can be divided by 51.

On to step 1:
The number 51 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 51

Step 2:
15 divided by 51 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 51

Advancing to step 3:
51 goes into 151 2 times with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 151 leaves us with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 51

On to step 4:
51 can be fit into 494 9 times, resulting in a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 459 from 494 leaves us with 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 51

Going ahead to step 5:
When dividing 355 by 51, we get 6 with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Deduct 306 from 355 and we're left with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 51

Let's proceed to step 6:
If we divide 497 by 51, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 2969.0
If we subtract 459 from 497, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
If we divide 380 by 51, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 2969.7
Deduct 357 from 380 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
230 divided by 51 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2969.74
If we take 204 away from 230, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
If we divide 260 by 51, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2969.745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 51, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 2969.745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
51 goes into 500 9 times with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 2969.74509
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 12:
410 divided by 51 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 2969.745098
Subtracting 408 from 410 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 51, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 2969.745098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
The number 51 fits into 200 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 2969.74509803
The remainder is 47 after subtracting 153 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 2969.74509803 and a remainder of 4.7e-08.
