We're dividing 20343391 by 351 
We want to figure out the number of times 20343391 can be divided by 351.

Advancing to step 1:
351 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 351

Going ahead to step 2:
351 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 351

Step 3:
The number 351 fits into 203 0 times, leaving a remainder of 203.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 203 after subtracting 0 from 203.
Include the next digit (4) from the dividend after 203, then repeat: 2034 / 351

Step 4:
When dividing 2034 by 351, we get 5 with a remainder of 279.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 1755 from 2034 and we're left with 279.
Include the next digit (3) from the dividend after 279, then repeat: 2793 / 351

Moving on to step 5:
The number 351 fits into 2793 7 times, leaving a remainder of 336.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 2457 from 2793 to get 336.
Take the next digit (3) from the dividend and append it to 336, then repeat: 3363 / 351

Let's proceed to step 6:
The number 351 fits into 3363 9 times, leaving a remainder of 204.
Write down 9 as next digit of the result. 
Result so far: 579.0
The remainder is 204 after subtracting 3159 from 3363.
Bring next digit (9) of the dividend behind the 204 and repeat the process: 2049 / 351

Let's proceed to step 7:
351 can be fit into 2049 5 times, resulting in a remainder of 294.
Write down 5 as next digit of the result. 
Result so far: 5795.0
Subtract 1755 from 2049 to get 294.
Grab the next digit (1) from the dividend, add it to 294, then carry on: 2941 / 351

Moving on to step 8:
The number 351 fits into 2941 8 times, leaving a remainder of 133.
Record the quotient 8 as the next digit in the result. 
Result so far: 57958.0
If we subtract 2808 from 2941, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 9:
The number 351 fits into 1330 3 times, leaving a remainder of 277.
Use 3 as the next digit of our solution. 
Result so far: 57958.3
If we take 1053 away from 1330, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 10:
2770 divided by 351 is 7 with a remainder of 313.
Put 7 as the next digit of the answer. 
Result so far: 57958.37
If we subtract 2457 from 2770, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 11:
351 can be fit into 3130 8 times, resulting in a remainder of 322.
The next digit of our result is 8. 
Result so far: 57958.378
Subtracting 2808 from 3130 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 12:
If we divide 3220 by 351, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 57958.3789
Subtract 3159 from 3220 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 13:
351 can be fit into 610 1 times, resulting in a remainder of 259.
The next digit of our result is 1. 
Result so far: 57958.37891
If we take 351 away from 610, we end up with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 14:
When dividing 2590 by 351, we get 7 with a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 57958.378917
If we subtract 2457 from 2590, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 15:
The number 351 fits into 1330 3 times, leaving a remainder of 277.
Record the quotient 3 as the next digit in the result. 
Result so far: 57958.3789173
If we subtract 1053 from 1330, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 16:
If we divide 2770 by 351, we get 7 and a remainder of 313.
The number 7 becomes the next digit in our result. 
Result so far: 57958.37891737
Subtracting 2457 from 2770 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Our division results in 57958.37891737 with a remaining 3.13e-07.
