45671231 divided by 858 
Let's see how many times 858 fits into 45671231.

On to step 1:
858 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 858

On to step 2:
858 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 858

Advancing to step 3:
456 divided by 858 is 0 with a remainder of 456.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 456 and we're left with 456.
Fetch the next digit (7) from the dividend, attach it to 456 and continue: 4567 / 858

Let's proceed to step 4:
858 goes into 4567 5 times with a remainder of 277.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4290 away from 4567, we end up with 277.
Fetch the next digit (1) from the dividend, attach it to 277 and continue: 2771 / 858

On to step 5:
When dividing 2771 by 858, we get 3 with a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 197 after subtracting 2574 from 2771.
Grab the next digit (2) from the dividend, add it to 197, then carry on: 1972 / 858

Step 6:
858 goes into 1972 2 times with a remainder of 256.
The next digit of our result is 2. 
Result so far: 532.0
Subtract 1716 from 1972 to get 256.
Fetch the next digit (3) from the dividend, attach it to 256 and continue: 2563 / 858

Moving on to step 7:
2563 divided by 858 is 2 with a remainder of 847.
Put 2 as the next digit of the answer. 
Result so far: 5322.0
Subtract 1716 from 2563 to get 847.
Bring next digit (1) of the dividend behind the 847 and repeat the process: 8471 / 858

Going ahead to step 8:
858 goes into 8471 9 times with a remainder of 749.
Write down 9 as next digit of the result. 
Result so far: 53229.0
The remainder is 749 after subtracting 7722 from 8471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Advancing to step 9:
858 goes into 7490 8 times with a remainder of 626.
Record the quotient 8 as the next digit in the result. 
Result so far: 53229.8
If we subtract 6864 from 7490, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 10:
When dividing 6260 by 858, we get 7 with a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 53229.87
If we subtract 6006 from 6260, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 11:
The number 858 fits into 2540 2 times, leaving a remainder of 824.
Write down 2 as next digit of the result. 
Result so far: 53229.872
If we subtract 1716 from 2540, we get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Let's proceed to step 12:
If we divide 8240 by 858, we get 9 and a remainder of 518.
Use 9 as the next digit of our solution. 
Result so far: 53229.8729
Subtracting 7722 from 8240 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 13:
If we divide 5180 by 858, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 53229.87296
Subtract 5148 from 5180 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 858 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 53229.87296
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
858 goes into 3200 3 times with a remainder of 626.
The number 3 becomes the next digit in our result. 
Result so far: 53229.8729603
If we subtract 2574 from 3200, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 16:
If we divide 6260 by 858, we get 7 and a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 53229.87296037
If we subtract 6006 from 6260, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

The quotient of the division is 53229.87296037, and the remainder is 2.54e-07.
