We look at the division of 42691660 by 860 
We want to figure out the number of times 42691660 can be divided by 860.

Step 1:
If we divide 4 by 860, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 860

Advancing to step 2:
When dividing 42 by 860, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 860

On to step 3:
If we divide 426 by 860, we get 0 and a remainder of 426.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 426 to get 426.
Fetch the next digit (9) from the dividend, attach it to 426 and continue: 4269 / 860

Going ahead to step 4:
If we divide 4269 by 860, we get 4 and a remainder of 829.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3440 from 4269 to get 829.
Take the next digit (1) from the dividend and append it to 829, then repeat: 8291 / 860

Let's proceed to step 5:
If we divide 8291 by 860, we get 9 and a remainder of 551.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 7740 from 8291 and we're left with 551.
Grab the next digit (6) from the dividend, add it to 551, then carry on: 5516 / 860

Going ahead to step 6:
860 can be fit into 5516 6 times, resulting in a remainder of 356.
The number 6 becomes the next digit in our result. 
Result so far: 496.0
If we subtract 5160 from 5516, we get 356.
Take the next digit (6) from the dividend and append it to 356, then repeat: 3566 / 860

Going ahead to step 7:
When dividing 3566 by 860, we get 4 with a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 4964.0
If we take 3440 away from 3566, we end up with 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 860

Moving on to step 8:
The number 860 fits into 1260 1 times, leaving a remainder of 400.
Use 1 as the next digit of our solution. 
Result so far: 49641.0
Deduct 860 from 1260 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 9:
860 can be fit into 4000 4 times, resulting in a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 49641.4
If we take 3440 away from 4000, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 10:
When dividing 5600 by 860, we get 6 with a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 49641.46
Subtracting 5160 from 5600 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 11:
860 goes into 4400 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 49641.465
Deduct 4300 from 4400 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
860 goes into 1000 1 times with a remainder of 140.
Write down 1 as next digit of the result. 
Result so far: 49641.4651
Subtract 860 from 1000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
860 goes into 1400 1 times with a remainder of 540.
Put 1 as the next digit of the answer. 
Result so far: 49641.46511
Subtract 860 from 1400 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The quotient of the division is 49641.46511, and the remainder is 0.00054.
