We look at the division of 20510430 by 388 
Let's see how many times 388 fits into 20510430.

Moving on to step 1:
When dividing 2 by 388, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 388

Step 2:
When dividing 20 by 388, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 388

Step 3:
388 can be fit into 205 0 times, resulting in a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Fetch the next digit (1) from the dividend, attach it to 205 and continue: 2051 / 388

Advancing to step 4:
When dividing 2051 by 388, we get 5 with a remainder of 111.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 1940 from 2051 to get 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 388

Let's proceed to step 5:
1110 divided by 388 is 2 with a remainder of 334.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 776 from 1110, we get 334.
Include the next digit (4) from the dividend after 334, then repeat: 3344 / 388

Step 6:
The number 388 fits into 3344 8 times, leaving a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 528.0
If we subtract 3104 from 3344, we get 240.
Fetch the next digit (3) from the dividend, attach it to 240 and continue: 2403 / 388

Let's proceed to step 7:
2403 divided by 388 is 6 with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 5286.0
Deduct 2328 from 2403 and we're left with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 388

Advancing to step 8:
750 divided by 388 is 1 with a remainder of 362.
The next digit of our result is 1. 
Result so far: 52861.0
Subtracting 388 from 750 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Going ahead to step 9:
388 goes into 3620 9 times with a remainder of 128.
Record the quotient 9 as the next digit in the result. 
Result so far: 52861.9
If we take 3492 away from 3620, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 10:
388 can be fit into 1280 3 times, resulting in a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 52861.93
Subtract 1164 from 1280 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 11:
1160 divided by 388 is 2 with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 52861.932
If we take 776 away from 1160, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 12:
When dividing 3840 by 388, we get 9 with a remainder of 348.
Put 9 as the next digit of the answer. 
Result so far: 52861.9329
Subtracting 3492 from 3840 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 13:
388 goes into 3480 8 times with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 52861.93298
Subtracting 3104 from 3480 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 14:
The number 388 fits into 3760 9 times, leaving a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 52861.932989
Subtracting 3492 from 3760 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 15:
388 can be fit into 2680 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 52861.9329896
Subtracting 2328 from 2680 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
The number 388 fits into 3520 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 52861.93298969
Subtract 3492 from 3520 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 52861.93298969, and the remainder is 2.8e-08.
