We're dividing 64459860 by 870 
Our goal is to divide 64459860 by 870.

Advancing to step 1:
870 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 870

On to step 2:
64 divided by 870 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 870

Step 3:
870 goes into 644 0 times with a remainder of 644.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 644 and we're left with 644.
Include the next digit (5) from the dividend after 644, then repeat: 6445 / 870

Let's proceed to step 4:
The number 870 fits into 6445 7 times, leaving a remainder of 355.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6090 from 6445 leaves us with 355.
Grab the next digit (9) from the dividend, add it to 355, then carry on: 3559 / 870

Going ahead to step 5:
870 goes into 3559 4 times with a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 3480 from 3559 and we're left with 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 870

Going ahead to step 6:
If we divide 798 by 870, we get 0 and a remainder of 798.
The next digit of our result is 0. 
Result so far: 740.0
Deduct 0 from 798 and we're left with 798.
Grab the next digit (6) from the dividend, add it to 798, then carry on: 7986 / 870

Moving on to step 7:
870 can be fit into 7986 9 times, resulting in a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 7409.0
Subtract 7830 from 7986 to get 156.
Bring next digit (0) of the dividend behind the 156 and repeat the process: 1560 / 870

Let's proceed to step 8:
1560 divided by 870 is 1 with a remainder of 690.
Write down 1 as next digit of the result. 
Result so far: 74091.0
If we subtract 870 from 1560, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 9:
When dividing 6900 by 870, we get 7 with a remainder of 810.
Use 7 as the next digit of our solution. 
Result so far: 74091.7
Deduct 6090 from 6900 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Let's proceed to step 10:
870 goes into 8100 9 times with a remainder of 270.
The next digit of our result is 9. 
Result so far: 74091.79
If we take 7830 away from 8100, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
2700 divided by 870 is 3 with a remainder of 90.
The number 3 becomes the next digit in our result. 
Result so far: 74091.793
Subtracting 2610 from 2700 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
When dividing 900 by 870, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 74091.7931
If we subtract 870 from 900, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
870 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 74091.7931
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
870 goes into 3000 3 times with a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 74091.793103
Deduct 2610 from 3000 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 15:
If we divide 3900 by 870, we get 4 and a remainder of 420.
Record the quotient 4 as the next digit in the result. 
Result so far: 74091.7931034
Deduct 3480 from 3900 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 16:
4200 divided by 870 is 4 with a remainder of 720.
Write down 4 as next digit of the result. 
Result so far: 74091.79310344
Deduct 3480 from 4200 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The quotient of the division is 74091.79310344, and the remainder is 7.2e-07.
