3467637 ÷ 212 
The aim is to understand the frequency of 212 in 3467637.

Going ahead to step 1:
When dividing 3 by 212, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 212

Step 2:
If we divide 34 by 212, we get 0 and a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 212

Let's proceed to step 3:
The number 212 fits into 346 1 times, leaving a remainder of 134.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 212 from 346 and we're left with 134.
Take the next digit (7) from the dividend and append it to 134, then repeat: 1347 / 212

Advancing to step 4:
212 can be fit into 1347 6 times, resulting in a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 1272 away from 1347, we end up with 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 212

Advancing to step 5:
When dividing 756 by 212, we get 3 with a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
The remainder is 120 after subtracting 636 from 756.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 212

On to step 6:
212 can be fit into 1203 5 times, resulting in a remainder of 143.
The number 5 becomes the next digit in our result. 
Result so far: 1635.0
If we take 1060 away from 1203, we end up with 143.
Bring next digit (7) of the dividend behind the 143 and repeat the process: 1437 / 212

Moving on to step 7:
If we divide 1437 by 212, we get 6 and a remainder of 165.
The next digit of our result is 6. 
Result so far: 16356.0
Deduct 1272 from 1437 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 8:
When dividing 1650 by 212, we get 7 with a remainder of 166.
Put 7 as the next digit of the answer. 
Result so far: 16356.7
Subtract 1484 from 1650 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
212 goes into 1660 7 times with a remainder of 176.
Use 7 as the next digit of our solution. 
Result so far: 16356.77
If we subtract 1484 from 1660, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final outcome is 16356.77, with a leftover of 0.176.
