We look at the division of 64889874 by 861 
We want to figure out the number of times 64889874 can be divided by 861.

Step 1:
861 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 861

Advancing to step 2:
64 divided by 861 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 861

On to step 3:
648 divided by 861 is 0 with a remainder of 648.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 648, we end up with 648.
Grab the next digit (8) from the dividend, add it to 648, then carry on: 6488 / 861

Step 4:
6488 divided by 861 is 7 with a remainder of 461.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 6027 away from 6488, we end up with 461.
Grab the next digit (9) from the dividend, add it to 461, then carry on: 4619 / 861

Let's proceed to step 5:
The number 861 fits into 4619 5 times, leaving a remainder of 314.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 4305 from 4619, we get 314.
Bring next digit (8) of the dividend behind the 314 and repeat the process: 3148 / 861

On to step 6:
861 goes into 3148 3 times with a remainder of 565.
The next digit of our result is 3. 
Result so far: 753.0
If we subtract 2583 from 3148, we get 565.
Take the next digit (7) from the dividend and append it to 565, then repeat: 5657 / 861

Step 7:
861 goes into 5657 6 times with a remainder of 491.
The next digit of our result is 6. 
Result so far: 7536.0
The remainder is 491 after subtracting 5166 from 5657.
Bring next digit (4) of the dividend behind the 491 and repeat the process: 4914 / 861

Let's proceed to step 8:
When dividing 4914 by 861, we get 5 with a remainder of 609.
Record the quotient 5 as the next digit in the result. 
Result so far: 75365.0
Subtract 4305 from 4914 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 9:
6090 divided by 861 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 75365.7
Subtracting 6027 from 6090 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 10:
If we divide 630 by 861, we get 0 and a remainder of 630.
Put 0 as the next digit of the answer. 
Result so far: 75365.7
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 11:
The number 861 fits into 6300 7 times, leaving a remainder of 273.
The next digit of our result is 7. 
Result so far: 75365.707
Subtracting 6027 from 6300 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Moving on to step 12:
If we divide 2730 by 861, we get 3 and a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 75365.7073
Deduct 2583 from 2730 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 13:
When dividing 1470 by 861, we get 1 with a remainder of 609.
Write down 1 as next digit of the result. 
Result so far: 75365.70731
Deduct 861 from 1470 and we're left with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Step 14:
If we divide 6090 by 861, we get 7 and a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 75365.707317
Subtract 6027 from 6090 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 15:
861 can be fit into 630 0 times, resulting in a remainder of 630.
Put 0 as the next digit of the answer. 
Result so far: 75365.707317
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 16:
When dividing 6300 by 861, we get 7 with a remainder of 273.
Put 7 as the next digit of the answer. 
Result so far: 75365.70731707
The remainder is 273 after subtracting 6027 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Our division results in 75365.70731707 with a remaining 2.73e-07.
