64535978 divided by 422 
The aim is to understand the frequency of 422 in 64535978.

Going ahead to step 1:
422 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 422

Let's proceed to step 2:
The number 422 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 422

Going ahead to step 3:
The number 422 fits into 645 1 times, leaving a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 422 away from 645, we end up with 223.
Fetch the next digit (3) from the dividend, attach it to 223 and continue: 2233 / 422

Going ahead to step 4:
If we divide 2233 by 422, we get 5 and a remainder of 123.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 123 after subtracting 2110 from 2233.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 422

Advancing to step 5:
The number 422 fits into 1235 2 times, leaving a remainder of 391.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we take 844 away from 1235, we end up with 391.
Bring next digit (9) of the dividend behind the 391 and repeat the process: 3919 / 422

Let's proceed to step 6:
If we divide 3919 by 422, we get 9 and a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 1529.0
Subtract 3798 from 3919 to get 121.
Bring next digit (7) of the dividend behind the 121 and repeat the process: 1217 / 422

Let's proceed to step 7:
1217 divided by 422 is 2 with a remainder of 373.
The number 2 becomes the next digit in our result. 
Result so far: 15292.0
If we subtract 844 from 1217, we get 373.
Grab the next digit (8) from the dividend, add it to 373, then carry on: 3738 / 422

Advancing to step 8:
422 can be fit into 3738 8 times, resulting in a remainder of 362.
Record the quotient 8 as the next digit in the result. 
Result so far: 152928.0
If we take 3376 away from 3738, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
422 goes into 3620 8 times with a remainder of 244.
Write down 8 as next digit of the result. 
Result so far: 152928.8
If we take 3376 away from 3620, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
If we divide 2440 by 422, we get 5 and a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 152928.85
Subtract 2110 from 2440 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 11:
422 can be fit into 3300 7 times, resulting in a remainder of 346.
Record the quotient 7 as the next digit in the result. 
Result so far: 152928.857
Deduct 2954 from 3300 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 12:
422 can be fit into 3460 8 times, resulting in a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 152928.8578
Deduct 3376 from 3460 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
If we divide 840 by 422, we get 1 and a remainder of 418.
Record the quotient 1 as the next digit in the result. 
Result so far: 152928.85781
Deduct 422 from 840 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 14:
When dividing 4180 by 422, we get 9 with a remainder of 382.
Record the quotient 9 as the next digit in the result. 
Result so far: 152928.857819
Deduct 3798 from 4180 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 15:
422 goes into 3820 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 152928.8578199
If we subtract 3798 from 3820, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 152928.8578199 with a remaining 2.2e-07.
