We divide 21057510 by 117
Our goal is to divide 21057510 by 117.

On to step 1:
117 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 117

Step 2:
If we divide 21 by 117, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 117

Advancing to step 3:
210 divided by 117 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 117 from 210 leaves us with 93.
Take the next digit (5) from the dividend and append it to 93, then repeat: 935 / 117

Advancing to step 4:
117 goes into 935 7 times with a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 819 away from 935, we end up with 116.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 117

Let's proceed to step 5:
If we divide 1167 by 117, we get 9 and a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtracting 1053 from 1167 leaves us with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 117

Step 6:
117 can be fit into 1145 9 times, resulting in a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 1799.0
Deduct 1053 from 1145 and we're left with 92.
Take the next digit (1) from the dividend and append it to 92, then repeat: 921 / 117

Moving on to step 7:
117 goes into 921 7 times with a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 17997.0
If we subtract 819 from 921, we get 102.
Take the next digit (0) from the dividend and append it to 102, then repeat: 1020 / 117

On to step 8:
If we divide 1020 by 117, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 179978.0
Subtracting 936 from 1020 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 9:
117 can be fit into 840 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 179978.7
If we take 819 away from 840, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
210 divided by 117 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 179978.71
If we take 117 away from 210, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 11:
117 can be fit into 930 7 times, resulting in a remainder of 111.
Record the quotient 7 as the next digit in the result. 
Result so far: 179978.717
If we take 819 away from 930, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 12:
117 can be fit into 1110 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 179978.7179
If we subtract 1053 from 1110, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
The number 117 fits into 570 4 times, leaving a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 179978.71794
Subtract 468 from 570 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 14:
The number 117 fits into 1020 8 times, leaving a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 179978.717948
Subtracting 936 from 1020 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 15:
The number 117 fits into 840 7 times, leaving a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 179978.7179487
Subtract 819 from 840 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 16:
117 goes into 210 1 times with a remainder of 93.
Record the quotient 1 as the next digit in the result. 
Result so far: 179978.71794871
Subtracting 117 from 210 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

The quotient of the division is 179978.71794871, and the remainder is 9.3e-08.
