64691602 ÷ 870 
We want to divide 64691602 by 870.

Step 1:
If we divide 6 by 870, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 870

Let's proceed to step 2:
The number 870 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 870

Going ahead to step 3:
870 goes into 646 0 times with a remainder of 646.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 646, we get 646.
Grab the next digit (9) from the dividend, add it to 646, then carry on: 6469 / 870

Let's proceed to step 4:
6469 divided by 870 is 7 with a remainder of 379.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 379 after subtracting 6090 from 6469.
Fetch the next digit (1) from the dividend, attach it to 379 and continue: 3791 / 870

Let's proceed to step 5:
870 can be fit into 3791 4 times, resulting in a remainder of 311.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 3480 from 3791 leaves us with 311.
Take the next digit (6) from the dividend and append it to 311, then repeat: 3116 / 870

Moving on to step 6:
870 can be fit into 3116 3 times, resulting in a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 743.0
If we subtract 2610 from 3116, we get 506.
Append the next digit (0) from the dividend to 506 and continue with: 5060 / 870

Advancing to step 7:
870 goes into 5060 5 times with a remainder of 710.
The number 5 becomes the next digit in our result. 
Result so far: 7435.0
Deduct 4350 from 5060 and we're left with 710.
Bring next digit (2) of the dividend behind the 710 and repeat the process: 7102 / 870

Going ahead to step 8:
When dividing 7102 by 870, we get 8 with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 74358.0
Deduct 6960 from 7102 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
870 goes into 1420 1 times with a remainder of 550.
The next digit of our result is 1. 
Result so far: 74358.1
The remainder is 550 after subtracting 870 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 10:
When dividing 5500 by 870, we get 6 with a remainder of 280.
The next digit of our result is 6. 
Result so far: 74358.16
If we take 5220 away from 5500, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
The number 870 fits into 2800 3 times, leaving a remainder of 190.
The number 3 becomes the next digit in our result. 
Result so far: 74358.163
Deduct 2610 from 2800 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 12:
When dividing 1900 by 870, we get 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 74358.1632
Deduct 1740 from 1900 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
The number 870 fits into 1600 1 times, leaving a remainder of 730.
Record the quotient 1 as the next digit in the result. 
Result so far: 74358.16321
The remainder is 730 after subtracting 870 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 14:
If we divide 7300 by 870, we get 8 and a remainder of 340.
The next digit of our result is 8. 
Result so far: 74358.163218
Subtracting 6960 from 7300 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 15:
If we divide 3400 by 870, we get 3 and a remainder of 790.
The number 3 becomes the next digit in our result. 
Result so far: 74358.1632183
If we subtract 2610 from 3400, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 16:
If we divide 7900 by 870, we get 9 and a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 74358.16321839
Subtract 7830 from 7900 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 74358.16321839 with a remaining 7e-08.
