87607407 divided by 213 
The aim is to understand the frequency of 213 in 87607407.

Going ahead to step 1:
If we divide 8 by 213, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 213

Moving on to step 2:
213 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 213

Advancing to step 3:
If we divide 876 by 213, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 852 from 876 and we're left with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 213

On to step 4:
213 can be fit into 240 1 times, resulting in a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 213 from 240 and we're left with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 213

Let's proceed to step 5:
The number 213 fits into 277 1 times, leaving a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 411.0
The remainder is 64 after subtracting 213 from 277.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 213

On to step 6:
If we divide 644 by 213, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 4113.0
If we take 639 away from 644, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 213

Moving on to step 7:
The number 213 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 41130.0
If we subtract 0 from 50, we get 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 213

Going ahead to step 8:
The number 213 fits into 507 2 times, leaving a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 411302.0
The remainder is 81 after subtracting 426 from 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
810 divided by 213 is 3 with a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 411302.3
If we subtract 639 from 810, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 10:
213 goes into 1710 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 411302.38
If we subtract 1704 from 1710, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
If we divide 60 by 213, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 411302.38
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
213 goes into 600 2 times with a remainder of 174.
The next digit of our result is 2. 
Result so far: 411302.3802
Subtracting 426 from 600 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 13:
1740 divided by 213 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 411302.38028
The remainder is 36 after subtracting 1704 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
213 goes into 360 1 times with a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 411302.380281
If we take 213 away from 360, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 15:
The number 213 fits into 1470 6 times, leaving a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 411302.3802816
Subtract 1278 from 1470 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
If we divide 1920 by 213, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 411302.38028169
Subtract 1917 from 1920 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 411302.38028169 with a balance of 3e-09.
