We look at the division of 9645437 by 77 
We want to figure out the number of times 9645437 can be divided by 77.

Moving on to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 77

On to step 2:
96 divided by 77 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we take 77 away from 96, we end up with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 77

Step 3:
77 goes into 194 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 154 from 194 leaves us with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 77

Advancing to step 4:
The number 77 fits into 405 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 385 from 405 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 77

On to step 5:
The number 77 fits into 204 2 times, leaving a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 1252.0
Subtracting 154 from 204 leaves us with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 77

Let's proceed to step 6:
When dividing 503 by 77, we get 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 12526.0
Subtracting 462 from 503 leaves us with 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 77

Step 7:
77 can be fit into 417 5 times, resulting in a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 125265.0
Subtract 385 from 417 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
77 can be fit into 320 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 125265.4
The remainder is 12 after subtracting 308 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 77, we get 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 125265.41
Deduct 77 from 120 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
77 can be fit into 430 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 125265.415
If we take 385 away from 430, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
450 divided by 77 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 125265.4155
If we subtract 385 from 450, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 125265.4155, and the remainder is 0.00065.
