21657549 ÷ 137 
We're looking to find how many times 137 goes into 21657549.

Advancing to step 1:
If we divide 2 by 137, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 137

Advancing to step 2:
When dividing 21 by 137, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 137

On to step 3:
If we divide 216 by 137, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 137 from 216, we get 79.
Grab the next digit (5) from the dividend, add it to 79, then carry on: 795 / 137

Going ahead to step 4:
795 divided by 137 is 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 685 from 795 leaves us with 110.
Include the next digit (7) from the dividend after 110, then repeat: 1107 / 137

Advancing to step 5:
When dividing 1107 by 137, we get 8 with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we take 1096 away from 1107, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 137

Moving on to step 6:
115 divided by 137 is 0 with a remainder of 115.
The number 0 becomes the next digit in our result. 
Result so far: 1580.0
Deduct 0 from 115 and we're left with 115.
Take the next digit (4) from the dividend and append it to 115, then repeat: 1154 / 137

Moving on to step 7:
137 can be fit into 1154 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 15808.0
Subtracting 1096 from 1154 leaves us with 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 137

Going ahead to step 8:
When dividing 589 by 137, we get 4 with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 158084.0
Deduct 548 from 589 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
The number 137 fits into 410 2 times, leaving a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 158084.2
The remainder is 136 after subtracting 274 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
If we divide 1360 by 137, we get 9 and a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 158084.29
Subtracting 1233 from 1360 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 11:
The number 137 fits into 1270 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 158084.299
Deduct 1233 from 1270 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 158084.299 and a remainder of 0.0037.
