We divide 3720383 by 213
The aim is to understand the frequency of 213 in 3720383.

Moving on to step 1:
If we divide 3 by 213, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 213

Moving on to step 2:
37 divided by 213 is 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 213

Moving on to step 3:
If we divide 372 by 213, we get 1 and a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 213 from 372 leaves us with 159.
Include the next digit (0) from the dividend after 159, then repeat: 1590 / 213

On to step 4:
213 can be fit into 1590 7 times, resulting in a remainder of 99.
The next digit of our result is 7. 
Result so far: 17.0
If we take 1491 away from 1590, we end up with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 213

Let's proceed to step 5:
If we divide 993 by 213, we get 4 and a remainder of 141.
Write down 4 as next digit of the result. 
Result so far: 174.0
Deduct 852 from 993 and we're left with 141.
Fetch the next digit (8) from the dividend, attach it to 141 and continue: 1418 / 213

Going ahead to step 6:
When dividing 1418 by 213, we get 6 with a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 1746.0
Subtract 1278 from 1418 to get 140.
Fetch the next digit (3) from the dividend, attach it to 140 and continue: 1403 / 213

On to step 7:
1403 divided by 213 is 6 with a remainder of 125.
Record the quotient 6 as the next digit in the result. 
Result so far: 17466.0
Subtract 1278 from 1403 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 8:
If we divide 1250 by 213, we get 5 and a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 17466.5
Subtracting 1065 from 1250 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
The number 213 fits into 1850 8 times, leaving a remainder of 146.
Put 8 as the next digit of the answer. 
Result so far: 17466.58
Deduct 1704 from 1850 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
When dividing 1460 by 213, we get 6 with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 17466.586
Subtract 1278 from 1460 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 11:
If we divide 1820 by 213, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 17466.5868
Deduct 1704 from 1820 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
When dividing 1160 by 213, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 17466.58685
If we take 1065 away from 1160, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
950 divided by 213 is 4 with a remainder of 98.
The number 4 becomes the next digit in our result. 
Result so far: 17466.586854
If we subtract 852 from 950, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 14:
980 divided by 213 is 4 with a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 17466.5868544
If we take 852 away from 980, 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.

Our division results in 17466.5868544 with a remaining 1.28e-06.
