We divide 401486 by 77
The aim is to understand the frequency of 77 in 401486.

Advancing to step 1:
The number 77 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 77

Step 2:
If we divide 40 by 77, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 77

Let's proceed to step 3:
401 divided by 77 is 5 with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 385 from 401 to get 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 77

On to step 4:
The number 77 fits into 164 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 154 from 164, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 77

Step 5:
When dividing 108 by 77, we get 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 521.0
Subtracting 77 from 108 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 77

Moving on to step 6:
77 goes into 316 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5214.0
Deduct 308 from 316 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 77 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 5214.1
Subtract 77 from 80 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.

On to step 8:
If we divide 30 by 77, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5214.1
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
300 divided by 77 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 5214.103
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
77 goes into 690 8 times with a remainder of 74.
The next digit of our result is 8. 
Result so far: 5214.1038
Subtract 616 from 690 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
When dividing 740 by 77, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 5214.10389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
77 can be fit into 470 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 5214.103896
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 77 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 5214.1038961
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
If we divide 30 by 77, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 5214.1038961
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 5214.1038961 with a remaining 3e-08.
