20598157 ÷ 210 
We're looking to find how many times 210 goes into 20598157.

Advancing to step 1:
210 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 210

Going ahead to step 2:
If we divide 20 by 210, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 210

Step 3:
If we divide 205 by 210, we get 0 and a remainder of 205.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Grab the next digit (9) from the dividend, add it to 205, then carry on: 2059 / 210

Going ahead to step 4:
210 can be fit into 2059 9 times, resulting in a remainder of 169.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 169 after subtracting 1890 from 2059.
Grab the next digit (8) from the dividend, add it to 169, then carry on: 1698 / 210

Step 5:
When dividing 1698 by 210, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtracting 1680 from 1698 leaves us with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 210

Step 6:
181 divided by 210 is 0 with a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 980.0
If we take 0 away from 181, we end up with 181.
Append the next digit (5) from the dividend to 181 and continue with: 1815 / 210

On to step 7:
1815 divided by 210 is 8 with a remainder of 135.
Use 8 as the next digit of our solution. 
Result so far: 9808.0
Subtracting 1680 from 1815 leaves us with 135.
Grab the next digit (7) from the dividend, add it to 135, then carry on: 1357 / 210

Going ahead to step 8:
If we divide 1357 by 210, we get 6 and a remainder of 97.
Record the quotient 6 as the next digit in the result. 
Result so far: 98086.0
Subtracting 1260 from 1357 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 9:
If we divide 970 by 210, we get 4 and a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 98086.4
Deduct 840 from 970 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
1300 divided by 210 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 98086.46
Subtract 1260 from 1300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
400 divided by 210 is 1 with a remainder of 190.
The number 1 becomes the next digit in our result. 
Result so far: 98086.461
Deduct 210 from 400 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 12:
When dividing 1900 by 210, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 98086.4619
Deduct 1890 from 1900 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
If we divide 100 by 210, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 98086.4619
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
The number 210 fits into 1000 4 times, leaving a remainder of 160.
Record the quotient 4 as the next digit in the result. 
Result so far: 98086.461904
If we subtract 840 from 1000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 15:
If we divide 1600 by 210, we get 7 and a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 98086.4619047
The remainder is 130 after subtracting 1470 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
1300 divided by 210 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 98086.46190476
If we take 1260 away from 1300, we end up 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.

The final result is 98086.46190476 with a remainder of 4e-08.
