Let's divide 21112188 by 161
We want to divide 21112188 by 161.

Let's proceed to step 1:
161 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 161

Let's proceed to step 2:
The number 161 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 161

Let's proceed to step 3:
211 divided by 161 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 161 away from 211, we end up with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 161

On to step 4:
When dividing 501 by 161, we get 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 483 from 501 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 161

Let's proceed to step 5:
161 can be fit into 182 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 131.0
The remainder is 21 after subtracting 161 from 182.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 161

On to step 6:
If we divide 211 by 161, we get 1 and a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1311.0
Subtract 161 from 211 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 161

Going ahead to step 7:
161 goes into 508 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 13113.0
Deduct 483 from 508 and we're left with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 161

Going ahead to step 8:
161 goes into 258 1 times with a remainder of 97.
The next digit of our result is 1. 
Result so far: 131131.0
Subtract 161 from 258 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 9:
The number 161 fits into 970 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 131131.6
Subtract 966 from 970 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 161 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 131131.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 161, we get 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 131131.602
Subtract 322 from 400 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
If we divide 780 by 161, we get 4 and a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 131131.6024
Subtract 644 from 780 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 13:
161 goes into 1360 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 131131.60248
If we take 1288 away from 1360, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 161 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 131131.602484
Subtract 644 from 720 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
The number 161 fits into 760 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 131131.6024844
Deduct 644 from 760 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

In conclusion, the division gives 131131.6024844 with a balance of 1.16e-06.
