We look at the division of 76637203 by 639 
The aim is to understand the frequency of 639 in 76637203.

Let's proceed to step 1:
If we divide 7 by 639, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 639

Advancing to step 2:
76 divided by 639 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 639

Let's proceed to step 3:
639 goes into 766 1 times with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 639 away from 766, we end up with 127.
Fetch the next digit (3) from the dividend, attach it to 127 and continue: 1273 / 639

Moving on to step 4:
639 goes into 1273 1 times with a remainder of 634.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 639 from 1273, we get 634.
Take the next digit (7) from the dividend and append it to 634, then repeat: 6347 / 639

Advancing to step 5:
6347 divided by 639 is 9 with a remainder of 596.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 5751 from 6347 and we're left with 596.
Take the next digit (2) from the dividend and append it to 596, then repeat: 5962 / 639

Going ahead to step 6:
If we divide 5962 by 639, we get 9 and a remainder of 211.
The number 9 becomes the next digit in our result. 
Result so far: 1199.0
The remainder is 211 after subtracting 5751 from 5962.
Take the next digit (0) from the dividend and append it to 211, then repeat: 2110 / 639

Advancing to step 7:
639 can be fit into 2110 3 times, resulting in a remainder of 193.
Use 3 as the next digit of our solution. 
Result so far: 11993.0
Subtracting 1917 from 2110 leaves us with 193.
Grab the next digit (3) from the dividend, add it to 193, then carry on: 1933 / 639

Advancing to step 8:
639 goes into 1933 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 119933.0
Subtract 1917 from 1933 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
639 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 119933.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
If we divide 1600 by 639, we get 2 and a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 119933.02
Subtract 1278 from 1600 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 11:
When dividing 3220 by 639, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 119933.025
If we take 3195 away from 3220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
When dividing 250 by 639, we get 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 119933.025
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
If we divide 2500 by 639, we get 3 and a remainder of 583.
Record the quotient 3 as the next digit in the result. 
Result so far: 119933.02503
Subtract 1917 from 2500 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 14:
639 goes into 5830 9 times with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 119933.025039
Deduct 5751 from 5830 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 15:
639 goes into 790 1 times with a remainder of 151.
Record the quotient 1 as the next digit in the result. 
Result so far: 119933.0250391
Deduct 639 from 790 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 16:
When dividing 1510 by 639, we get 2 with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 119933.02503912
If we take 1278 away from 1510, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 119933.02503912 with a remaining 2.32e-07.
