Let's divide 61455778 by 870
We want to figure out the number of times 61455778 can be divided by 870.

On to step 1:
870 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 870

Moving on to step 2:
The number 870 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 870

Advancing to step 3:
If we divide 614 by 870, we get 0 and a remainder of 614.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 614 to get 614.
Grab the next digit (5) from the dividend, add it to 614, then carry on: 6145 / 870

Let's proceed to step 4:
The number 870 fits into 6145 7 times, leaving a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 55 after subtracting 6090 from 6145.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 870

Step 5:
870 can be fit into 555 0 times, resulting in a remainder of 555.
The next digit of our result is 0. 
Result so far: 70.0
If we take 0 away from 555, we end up with 555.
Include the next digit (7) from the dividend after 555, then repeat: 5557 / 870

Going ahead to step 6:
5557 divided by 870 is 6 with a remainder of 337.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
If we take 5220 away from 5557, we end up with 337.
Append the next digit (7) from the dividend to 337 and continue with: 3377 / 870

Going ahead to step 7:
870 goes into 3377 3 times with a remainder of 767.
Use 3 as the next digit of our solution. 
Result so far: 7063.0
Subtracting 2610 from 3377 leaves us with 767.
Include the next digit (8) from the dividend after 767, then repeat: 7678 / 870

Let's proceed to step 8:
When dividing 7678 by 870, we get 8 with a remainder of 718.
Use 8 as the next digit of our solution. 
Result so far: 70638.0
If we subtract 6960 from 7678, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 9:
The number 870 fits into 7180 8 times, leaving a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 70638.8
Subtracting 6960 from 7180 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
870 can be fit into 2200 2 times, resulting in a remainder of 460.
Record the quotient 2 as the next digit in the result. 
Result so far: 70638.82
If we subtract 1740 from 2200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 11:
870 goes into 4600 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 70638.825
Subtract 4350 from 4600 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
870 goes into 2500 2 times with a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 70638.8252
If we take 1740 away from 2500, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 13:
7600 divided by 870 is 8 with a remainder of 640.
Use 8 as the next digit of our solution. 
Result so far: 70638.82528
If we take 6960 away from 7600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
6400 divided by 870 is 7 with a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 70638.825287
Subtracting 6090 from 6400 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 15:
The number 870 fits into 3100 3 times, leaving a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 70638.8252873
If we subtract 2610 from 3100, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Going ahead to step 16:
The number 870 fits into 4900 5 times, leaving a remainder of 550.
Record the quotient 5 as the next digit in the result. 
Result so far: 70638.82528735
If we subtract 4350 from 4900, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 70638.82528735 and a remainder of 5.5e-07.
