64609794 ÷ 857 
We're looking to find how many times 857 goes into 64609794.

Advancing to step 1:
When dividing 6 by 857, we get 0 with 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 857

Advancing to step 2:
When dividing 64 by 857, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 857

Moving on to step 3:
646 divided by 857 is 0 with a remainder of 646.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 646 to get 646.
Fetch the next digit (0) from the dividend, attach it to 646 and continue: 6460 / 857

Advancing to step 4:
6460 divided by 857 is 7 with a remainder of 461.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 5999 from 6460 to get 461.
Fetch the next digit (9) from the dividend, attach it to 461 and continue: 4619 / 857

Advancing to step 5:
857 can be fit into 4619 5 times, resulting in a remainder of 334.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtract 4285 from 4619 to get 334.
Append the next digit (7) from the dividend to 334 and continue with: 3347 / 857

Step 6:
The number 857 fits into 3347 3 times, leaving a remainder of 776.
The number 3 becomes the next digit in our result. 
Result so far: 753.0
If we take 2571 away from 3347, we end up with 776.
Take the next digit (9) from the dividend and append it to 776, then repeat: 7769 / 857

Moving on to step 7:
857 can be fit into 7769 9 times, resulting in a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 7539.0
If we subtract 7713 from 7769, we get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 857

Advancing to step 8:
When dividing 564 by 857, we get 0 with a remainder of 564.
Use 0 as the next digit of our solution. 
Result so far: 75390.0
If we take 0 away from 564, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 9:
857 can be fit into 5640 6 times, resulting in a remainder of 498.
The number 6 becomes the next digit in our result. 
Result so far: 75390.6
If we subtract 5142 from 5640, we get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 10:
If we divide 4980 by 857, we get 5 and a remainder of 695.
Record the quotient 5 as the next digit in the result. 
Result so far: 75390.65
Deduct 4285 from 4980 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 11:
When dividing 6950 by 857, we get 8 with a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 75390.658
Subtracting 6856 from 6950 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
If we divide 940 by 857, we get 1 and a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 75390.6581
Subtracting 857 from 940 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 13:
When dividing 830 by 857, we get 0 with a remainder of 830.
Use 0 as the next digit of our solution. 
Result so far: 75390.6581
If we subtract 0 from 830, we get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Step 14:
857 goes into 8300 9 times with a remainder of 587.
Use 9 as the next digit of our solution. 
Result so far: 75390.658109
Subtract 7713 from 8300 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 15:
857 goes into 5870 6 times with a remainder of 728.
The next digit of our result is 6. 
Result so far: 75390.6581096
The remainder is 728 after subtracting 5142 from 5870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 16:
If we divide 7280 by 857, we get 8 and a remainder of 424.
Write down 8 as next digit of the result. 
Result so far: 75390.65810968
The remainder is 424 after subtracting 6856 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 75390.65810968, with a leftover of 4.24e-07.
