We look at the division of 57053147 by 402 
We want to figure out the number of times 57053147 can be divided by 402.

Step 1:
When dividing 5 by 402, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 402

Advancing to step 2:
402 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 402

Advancing to step 3:
402 can be fit into 570 1 times, resulting in a remainder of 168.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 402 from 570 to get 168.
Include the next digit (5) from the dividend after 168, then repeat: 1685 / 402

Let's proceed to step 4:
If we divide 1685 by 402, we get 4 and a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1608 from 1685 leaves us with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 402

Going ahead to step 5:
402 can be fit into 773 1 times, resulting in a remainder of 371.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtract 402 from 773 to get 371.
Bring next digit (1) of the dividend behind the 371 and repeat the process: 3711 / 402

Moving on to step 6:
3711 divided by 402 is 9 with a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 1419.0
Subtract 3618 from 3711 to get 93.
Grab the next digit (4) from the dividend, add it to 93, then carry on: 934 / 402

Moving on to step 7:
934 divided by 402 is 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 14192.0
Subtract 804 from 934 to get 130.
Bring next digit (7) of the dividend behind the 130 and repeat the process: 1307 / 402

Moving on to step 8:
1307 divided by 402 is 3 with a remainder of 101.
The number 3 becomes the next digit in our result. 
Result so far: 141923.0
If we subtract 1206 from 1307, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
402 goes into 1010 2 times with a remainder of 206.
The next digit of our result is 2. 
Result so far: 141923.2
If we take 804 away from 1010, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
If we divide 2060 by 402, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 141923.25
Deduct 2010 from 2060 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
The number 402 fits into 500 1 times, leaving a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 141923.251
The remainder is 98 after subtracting 402 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
When dividing 980 by 402, we get 2 with a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 141923.2512
Subtract 804 from 980 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
402 can be fit into 1760 4 times, resulting in a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 141923.25124
Deduct 1608 from 1760 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
1520 divided by 402 is 3 with a remainder of 314.
Put 3 as the next digit of the answer. 
Result so far: 141923.251243
Subtracting 1206 from 1520 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 15:
If we divide 3140 by 402, we get 7 and a remainder of 326.
The next digit of our result is 7. 
Result so far: 141923.2512437
Subtract 2814 from 3140 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 16:
The number 402 fits into 3260 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 141923.25124378
Deduct 3216 from 3260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 141923.25124378, with a leftover of 4.4e-08.
