57765217 divided by 61 
We want to figure out the number of times 57765217 can be divided by 61.

Step 1:
If we divide 5 by 61, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 61

Let's proceed to step 2:
61 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 61

Going ahead to step 3:
The number 61 fits into 577 9 times, leaving a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 28 after subtracting 549 from 577.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 61

Advancing to step 4:
When dividing 286 by 61, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 244 from 286 and we're left with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 61

Let's proceed to step 5:
425 divided by 61 is 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 946.0
Subtracting 366 from 425 leaves us with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 61

Advancing to step 6:
If we divide 592 by 61, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 9469.0
Deduct 549 from 592 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 61

On to step 7:
The number 61 fits into 431 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 94697.0
Subtracting 427 from 431 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 61

Going ahead to step 8:
61 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 946970.0
Deduct 0 from 47 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 9:
61 goes into 470 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 946970.7
Subtracting 427 from 470 leaves us 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.

Let's proceed to step 10:
If we divide 430 by 61, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 946970.77
Subtracting 427 from 430 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.

The final outcome is 946970.77, with a leftover of 0.003.
