64512080 ÷ 629 
The aim is to understand the frequency of 629 in 64512080.

Advancing to step 1:
629 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 629

Advancing to step 2:
629 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 629

Going ahead to step 3:
If we divide 645 by 629, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 629 from 645 leaves us with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 629

Going ahead to step 4:
When dividing 161 by 629, we get 0 with a remainder of 161.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 161 after subtracting 0 from 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 629

Moving on to step 5:
1612 divided by 629 is 2 with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1258 from 1612 to get 354.
Append the next digit (0) from the dividend to 354 and continue with: 3540 / 629

Step 6:
When dividing 3540 by 629, we get 5 with a remainder of 395.
The next digit of our result is 5. 
Result so far: 1025.0
Subtract 3145 from 3540 to get 395.
Grab the next digit (8) from the dividend, add it to 395, then carry on: 3958 / 629

Step 7:
629 goes into 3958 6 times with a remainder of 184.
The next digit of our result is 6. 
Result so far: 10256.0
The remainder is 184 after subtracting 3774 from 3958.
Bring next digit (0) of the dividend behind the 184 and repeat the process: 1840 / 629

Going ahead to step 8:
629 can be fit into 1840 2 times, resulting in a remainder of 582.
Use 2 as the next digit of our solution. 
Result so far: 102562.0
If we subtract 1258 from 1840, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 9:
If we divide 5820 by 629, we get 9 and a remainder of 159.
Use 9 as the next digit of our solution. 
Result so far: 102562.9
The remainder is 159 after subtracting 5661 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 10:
When dividing 1590 by 629, we get 2 with a remainder of 332.
Record the quotient 2 as the next digit in the result. 
Result so far: 102562.92
Subtracting 1258 from 1590 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
When dividing 3320 by 629, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 102562.925
If we subtract 3145 from 3320, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 12:
629 goes into 1750 2 times with a remainder of 492.
Use 2 as the next digit of our solution. 
Result so far: 102562.9252
If we take 1258 away from 1750, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Moving on to step 13:
The number 629 fits into 4920 7 times, leaving a remainder of 517.
Write down 7 as next digit of the result. 
Result so far: 102562.92527
Subtract 4403 from 4920 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Step 14:
If we divide 5170 by 629, we get 8 and a remainder of 138.
Record the quotient 8 as the next digit in the result. 
Result so far: 102562.925278
If we take 5032 away from 5170, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 15:
629 can be fit into 1380 2 times, resulting in a remainder of 122.
The next digit of our result is 2. 
Result so far: 102562.9252782
If we subtract 1258 from 1380, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 16:
The number 629 fits into 1220 1 times, leaving a remainder of 591.
Put 1 as the next digit of the answer. 
Result so far: 102562.92527821
Subtracting 629 from 1220 leaves us with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Our division results in 102562.92527821 with a remaining 5.91e-07.
