721214 divided by 37 
The aim is to understand the frequency of 37 in 721214.

On to step 1:
37 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 37

Moving on to step 2:
If we divide 72 by 37, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 37 from 72 leaves us with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 37

Advancing to step 3:
37 can be fit into 351 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 333 from 351 and we're left with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 37

Going ahead to step 4:
182 divided by 37 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 194.0
Deduct 148 from 182 and we're left with 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 37

Moving on to step 5:
341 divided by 37 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 1949.0
If we subtract 333 from 341, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 37

On to step 6:
The number 37 fits into 84 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 19492.0
Subtracting 74 from 84 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 37 fits into 100 2 times, leaving a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 19492.2
Subtracting 74 from 100 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
When dividing 260 by 37, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 19492.27
If we subtract 259 from 260, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
37 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 19492.27
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 37, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 19492.2702
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
37 goes into 260 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 19492.27027
If we take 259 away from 260, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
37 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19492.27027
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
100 divided by 37 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 19492.2702702
Deduct 74 from 100 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
37 goes into 260 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 19492.27027027
Deduct 259 from 260 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 19492.27027027 and a remainder of 1e-09.
