We divide 20531251 by 977
The aim is to understand the frequency of 977 in 20531251.

Going ahead to step 1:
2 divided by 977 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 977

Advancing to step 2:
977 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 977

Moving on to step 3:
205 divided by 977 is 0 with a remainder of 205.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Grab the next digit (3) from the dividend, add it to 205, then carry on: 2053 / 977

Advancing to step 4:
977 goes into 2053 2 times with a remainder of 99.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1954 from 2053 to get 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 977

On to step 5:
991 divided by 977 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 977 away from 991, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 977

On to step 6:
977 can be fit into 142 0 times, resulting in a remainder of 142.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtract 0 from 142 to get 142.
Fetch the next digit (5) from the dividend, attach it to 142 and continue: 1425 / 977

Moving on to step 7:
1425 divided by 977 is 1 with a remainder of 448.
The number 1 becomes the next digit in our result. 
Result so far: 2101.0
Subtract 977 from 1425 to get 448.
Take the next digit (1) from the dividend and append it to 448, then repeat: 4481 / 977

Step 8:
977 goes into 4481 4 times with a remainder of 573.
Record the quotient 4 as the next digit in the result. 
Result so far: 21014.0
Deduct 3908 from 4481 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Going ahead to step 9:
If we divide 5730 by 977, we get 5 and a remainder of 845.
The number 5 becomes the next digit in our result. 
Result so far: 21014.5
Subtracting 4885 from 5730 leaves us with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Going ahead to step 10:
977 goes into 8450 8 times with a remainder of 634.
Put 8 as the next digit of the answer. 
Result so far: 21014.58
Subtract 7816 from 8450 to get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 11:
The number 977 fits into 6340 6 times, leaving a remainder of 478.
Put 6 as the next digit of the answer. 
Result so far: 21014.586
Subtract 5862 from 6340 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 12:
If we divide 4780 by 977, we get 4 and a remainder of 872.
Use 4 as the next digit of our solution. 
Result so far: 21014.5864
The remainder is 872 after subtracting 3908 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Moving on to step 13:
When dividing 8720 by 977, we get 8 with a remainder of 904.
Use 8 as the next digit of our solution. 
Result so far: 21014.58648
If we subtract 7816 from 8720, we get 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

On to step 14:
The number 977 fits into 9040 9 times, leaving a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 21014.586489
Subtracting 8793 from 9040 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 15:
The number 977 fits into 2470 2 times, leaving a remainder of 516.
The next digit of our result is 2. 
Result so far: 21014.5864892
Deduct 1954 from 2470 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 16:
When dividing 5160 by 977, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 21014.58648925
Deduct 4885 from 5160 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The quotient of the division is 21014.58648925, and the remainder is 2.75e-07.
