We divide 61515985 by 977
The aim is to understand the frequency of 977 in 61515985.

Advancing to step 1:
If we divide 6 by 977, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 977

On to step 2:
977 goes into 61 0 times with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 977

Moving on to step 3:
The number 977 fits into 615 0 times, leaving a remainder of 615.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 615, we end up with 615.
Bring next digit (1) of the dividend behind the 615 and repeat the process: 6151 / 977

Moving on to step 4:
If we divide 6151 by 977, we get 6 and a remainder of 289.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5862 away from 6151, we end up with 289.
Grab the next digit (5) from the dividend, add it to 289, then carry on: 2895 / 977

Step 5:
If we divide 2895 by 977, we get 2 and a remainder of 941.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 1954 away from 2895, we end up with 941.
Append the next digit (9) from the dividend to 941 and continue with: 9419 / 977

Let's proceed to step 6:
977 can be fit into 9419 9 times, resulting in a remainder of 626.
Use 9 as the next digit of our solution. 
Result so far: 629.0
The remainder is 626 after subtracting 8793 from 9419.
Grab the next digit (8) from the dividend, add it to 626, then carry on: 6268 / 977

Let's proceed to step 7:
If we divide 6268 by 977, we get 6 and a remainder of 406.
Use 6 as the next digit of our solution. 
Result so far: 6296.0
Subtract 5862 from 6268 to get 406.
Take the next digit (5) from the dividend and append it to 406, then repeat: 4065 / 977

Step 8:
When dividing 4065 by 977, we get 4 with a remainder of 157.
The next digit of our result is 4. 
Result so far: 62964.0
The remainder is 157 after subtracting 3908 from 4065.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
The number 977 fits into 1570 1 times, leaving a remainder of 593.
Record the quotient 1 as the next digit in the result. 
Result so far: 62964.1
Deduct 977 from 1570 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

On to step 10:
5930 divided by 977 is 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 62964.16
Subtracting 5862 from 5930 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
When dividing 680 by 977, we get 0 with a remainder of 680.
The next digit of our result is 0. 
Result so far: 62964.16
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 12:
If we divide 6800 by 977, we get 6 and a remainder of 938.
Put 6 as the next digit of the answer. 
Result so far: 62964.1606
If we take 5862 away from 6800, we end up with 938.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9380, and continue the process.

On to step 13:
When dividing 9380 by 977, we get 9 with a remainder of 587.
The number 9 becomes the next digit in our result. 
Result so far: 62964.16069
Deduct 8793 from 9380 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Advancing to step 14:
977 can be fit into 5870 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 62964.160696
Subtract 5862 from 5870 to 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.

Step 15:
When dividing 80 by 977, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 62964.160696
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
If we divide 800 by 977, we get 0 and a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 62964.160696
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 62964.160696 with a remaining 8e-07.
