We look at the division of 97977143 by 870 
We want to divide 97977143 by 870.

Moving on to step 1:
870 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 870

Let's proceed to step 2:
870 goes into 97 0 times with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 870

Advancing to step 3:
979 divided by 870 is 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 870 from 979, we get 109.
Grab the next digit (7) from the dividend, add it to 109, then carry on: 1097 / 870

On to step 4:
When dividing 1097 by 870, we get 1 with a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 870 from 1097, we get 227.
Bring next digit (7) of the dividend behind the 227 and repeat the process: 2277 / 870

Going ahead to step 5:
When dividing 2277 by 870, we get 2 with a remainder of 537.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1740 from 2277 to get 537.
Include the next digit (1) from the dividend after 537, then repeat: 5371 / 870

Going ahead to step 6:
870 goes into 5371 6 times with a remainder of 151.
Use 6 as the next digit of our solution. 
Result so far: 1126.0
The remainder is 151 after subtracting 5220 from 5371.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 870

Let's proceed to step 7:
870 goes into 1514 1 times with a remainder of 644.
Record the quotient 1 as the next digit in the result. 
Result so far: 11261.0
The remainder is 644 after subtracting 870 from 1514.
Fetch the next digit (3) from the dividend, attach it to 644 and continue: 6443 / 870

Advancing to step 8:
870 can be fit into 6443 7 times, resulting in a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 112617.0
Deduct 6090 from 6443 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 9:
The number 870 fits into 3530 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 112617.4
Deduct 3480 from 3530 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
The number 870 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 112617.4
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
870 can be fit into 5000 5 times, resulting in a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 112617.405
Subtract 4350 from 5000 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 12:
When dividing 6500 by 870, we get 7 with a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 112617.4057
Subtract 6090 from 6500 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 13:
4100 divided by 870 is 4 with a remainder of 620.
The number 4 becomes the next digit in our result. 
Result so far: 112617.40574
Subtract 3480 from 4100 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 14:
The number 870 fits into 6200 7 times, leaving a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 112617.405747
Deduct 6090 from 6200 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
When dividing 1100 by 870, we get 1 with a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 112617.4057471
Subtract 870 from 1100 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
If we divide 2300 by 870, we get 2 and a remainder of 560.
The next digit of our result is 2. 
Result so far: 112617.40574712
The remainder is 560 after subtracting 1740 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 112617.40574712 and a remainder of 5.6e-07.
