20104042 divided by 213 
We're looking to find how many times 213 goes into 20104042.

Moving on to step 1:
The number 213 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
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 / 213

Step 2:
213 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 213

Advancing to step 3:
If we divide 201 by 213, we get 0 and a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 201 after subtracting 0 from 201.
Fetch the next digit (0) from the dividend, attach it to 201 and continue: 2010 / 213

Going ahead to step 4:
213 can be fit into 2010 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 1917 from 2010 to get 93.
Append the next digit (4) from the dividend to 93 and continue with: 934 / 213

Going ahead to step 5:
213 goes into 934 4 times with a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 852 from 934 and we're left with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 213

Advancing to step 6:
213 goes into 820 3 times with a remainder of 181.
The next digit of our result is 3. 
Result so far: 943.0
Deduct 639 from 820 and we're left with 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 213

Going ahead to step 7:
1814 divided by 213 is 8 with a remainder of 110.
The next digit of our result is 8. 
Result so far: 9438.0
If we take 1704 away from 1814, we end up with 110.
Fetch the next digit (2) from the dividend, attach it to 110 and continue: 1102 / 213

Step 8:
If we divide 1102 by 213, we get 5 and a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 94385.0
If we subtract 1065 from 1102, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
When dividing 370 by 213, we get 1 with a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 94385.1
Subtract 213 from 370 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 10:
213 goes into 1570 7 times with a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 94385.17
Subtracting 1491 from 1570 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 11:
213 can be fit into 790 3 times, resulting in a remainder of 151.
The next digit of our result is 3. 
Result so far: 94385.173
If we subtract 639 from 790, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 12:
The number 213 fits into 1510 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 94385.1737
Deduct 1491 from 1510 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 213 fits into 190 0 times, leaving a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 94385.1737
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
1900 divided by 213 is 8 with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 94385.173708
If we subtract 1704 from 1900, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 15:
213 can be fit into 1960 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 94385.1737089
The remainder is 43 after subtracting 1917 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 16:
The number 213 fits into 430 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 94385.17370892
If we take 426 away from 430, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 94385.17370892, with a leftover of 4e-09.
